ADF Application Process

File:ADF Recruitment Journey.png

Visual overview of the five stages of the ADF recruitment pipeline.

Stage 1: The Online Application & Aptitude Test

This is the very start of the application process to become an ADF member. To be able to apply, the candidate is required to be at the age of 16.5 and above, an Australian citizen (both the candidate and parents) and if so then to create an account through the ADF Careers website. Once clicked the link the candidate is required to fill out a form, the form will ask you the following.

• Name
• Date of birth (DOB)
• Citizenship
• Email
• Phone
• Parents Citizenship
• ADF branch preference
• 3 preferences on roles

Once that has been filled out the candidate will be sent an email in the next 2-3 business days that includes the Job Opportunities Assessment (JOA). After the candidate gets that email they are required to complete the JOA, there is usually a certain time frame that it needs to be completed by as it should say in the email if it's not completed by then the candidate is to then call them and request a new link. Once the candidate has completed the JOA they will then be sent another email with their Job Opportunities Results (JOR) and will also be introduced to their case manager. With the JOR there will be a PDF attached and this essentially lets the candidate know what roles they have unlocked.[1]

Stage 2: The Assessment Session

With stage 2 of the process the candidate will get an email or text from their case manager. In the email it will let you know that your career coaching call has been booked and will say something along the lines of "Your career coaching call has been booked for Day/Month/Year" if this time that they have booked the career coaching call is inconvenient the candidate is to call and reschedule for another day.

On the day of the call 3-4 hours before the candidate is emailed a virtual link to a face-to-face online call but depending on the case manager they might give the candidate the option to do it via phone. In this call the candidate is told about the rules of the ADF like "Do you fully agree that you are ready to be deployed at anytime even on very short notice" and "Even though you are in the Australian Defence Force anything illegal that you do you will still be prosecuted by the normal Australian laws" once you accept that you will be asked the following listed below.

• Any previous criminal offences
• If you are aware of the fitness requirements
• Reason for wanting to join the ADF
• If under the age of 18 if you have told your parents
• If your family, parents approve / encourage
• Do you have a partner or children

Once the candidate has gone through that the call is then disconnected and then the candidate will wait for the next steps. When there is another email after the career coaching call it will ask the candidate to fill out the following on their candidate hub.

• Birth certificate
• Parent birth certificate
• Drivers license
• Passport
• Year 10 and 11 school reports
• Proof of ID (another form of identification)

when done the candidate goes through Stage 3.

Stage 3: ADF Careers Interview

When the candidate has completed all of the other stages before this they are then to contact their case manager and notify them that they are ready to attend the assessment day at the ADF career centre. Once done the case manager will call the candidate and walk them through everything that is going to happen when they attend their assessment at the ADF career centre and will give you tips and tricks. When the candidate attends their assessment day they will go through 3 parts: the Interview, psychological interview and medical assessment.

Medical assessment

In the medical assessment the staff will record your height, weight and body mass index they will also do a hearing test in a soundproof room and will examine both of your eyes for color blindness and visual clarity.

The candidate will then be required to strip down to their underwear then the doctor will check blood pressure, listen to heart and lungs and examine reflexes and posture.

Then they will get the candidate to perform specific movements so that they can test their joint health and stability and then also check your hips, knees and ankles.

Then they collect pee samples to check for kidney function indications of underlying conditions and for any previous use of prohibited substances.

Psychological Interview

In the psychological interview they will review the candidates life history this includes education history, employment stability, family dynamics and social support.

Then they will ask specific questions like about the candidates daily routine to see what your daily productivity and motivation is, they will heavily explore past experiences with stress and ask how the candidate manages high pressure situations.

The final part for this the candidate will be asked blunt questions like the candidates willingness to live away from home, how they adapt to restricted environments, accept every lawful command and potentially use lethal force inside a combat zone.

Defence interview

In the defence interview the candidate is required to recite technical facts about the chosen position like the specific weapon systems, equipment used, the duration of the initial military training (IMT) and the location of the IMT schools.

The candidate is also to be required to display a clear understanding of the military lifestyle including minimum service periods and all of the posting locations across Australia and the potential risk of getting deployed.

Stage 4: The Physical Fitness Test (PFA)

Physical Fitness Assessment (PFA)

The PFA measures the candidates basic physical capabilities to make sure that they can survive the IMT. The requirements do vary per branch according to the ADF Careers 2026 Entry Standards.

Australian Defence Force Entry Fitness Requirements

Service Branch	Push-ups Requirement	Sit-ups Requirement (Feet Held)	Shuttle Run (Beep Test) Level
Royal Australian Navy	15 (Male) / 6 (Female)	25 (Both)	6.1 (Both)
Australian Army (Support)	15 (Both)	45 (Both)	7.5 (Both)
Australian Army (Combat/Officer)	15 (Male) / 15 (Female)	45 (Both)	7.5 (Both)
Royal Australian Air Force	N/A (Not scored for standard entry)	20 (Both)	6.1 (Male) / 5.1 (Female)

Stage 5: Selection Board & Enlistment

The Australian Defence Force ranks candidates against all other applicants nationwide who are competing for the same trade. This ranking is calculated based on performance scores achieved during the aptitude testing, psychological interview, and medical evaluation.

When a training vacancy opens up at a recruit school, the recruitment team selects the highest-ranked candidates from the pool. An Enlistment Coordinator contacts the candidate to make a formal job offer, which is followed by an official Letter of Offer detailing their pay scale, minimum service period, and designated enlistment date.

Enlistment Day

Candidates taking the formal Oath or Affirmation before a commissioning officer.

Enlistment Day (Generel Entery)

The candidate undergoes a rapid, final medical review upon arrival. This screening ensures the candidate has not sustained any new injuries, developed illnesses, or experienced major health changes since their primary assessment day.

The candidate meets with administrative staff to complete their final onboarding paperwork. This includes signing their official service contracts, confirming banking details for salary processing, submitting tax file numbers, and verifying emergency contacts.

Family and friends are invited to witness the formal induction. The candidate stands before a commissioning officer to make either a religious Oath or a secular Affirmation of allegiance to the Sovereign. Signing the enlistment document legally binds the candidate to military service under Defence law.

Following a brief period to say farewell to their guests, the newly enlisted recruits are marshalled by military staff. The candidate is then transported directly via bus or flight to their respective initial recruit training bases—such as the Army Recruit Training Centre at Kapooka, HMAS Cerberus for the Navy, or 1RTU for the Air Force.

Enlistment day (Officer Entry)

The candidate undergoes a rapid, final medical review upon arrival. This screening ensures the candidate has not sustained any new injuries, developed illnesses, or experienced major health changes since their primary assessment day.

The candidate meets with administrative staff to complete their final onboarding paperwork. This includes signing their official commissioning and appointment documents, confirming banking details for salary processing, submitting tax file numbers, and verifying emergency contacts.

Family and friends are invited to witness the formal induction. The candidate stands before a senior commissioning officer to make either a religious Oath or a secular Affirmation of allegiance to the Sovereign. Signing the appointment document legally binds the candidate to military service as an officer under Defence law.

Following a brief period to say farewell to their guests, the newly appointed officers are marshalled by military staff. The candidate is then transported directly via bus or flight to their respective initial officer training institutions—such as the Royal Military College (RMC) Duntroon for the Army, the Royal Australian Naval College (RANC) HMAS Creswell for the Navy, or the Officers' Training School (OTS) at RAAF Base East Sale for the Air Force.

Within the application process of joining the Australian Defence Force (ADF) there is a Medical questionnaire that all candidates are required to fill out before you can go for your assessment session and fitness assessment and then enlist in the Defence Force.

All ADF Medical Classifications

Class 1 (Medically Fit)

This class is for candidates that are fully physically and mentally fit for ADF. This is given to candidates that are not "suffering" from any medical conditions and who don't have any injuries that can be easily aggravated while serving in the ADF.

Class 2 (Fit with Waiver)

Class 2 is what the ADF gives to candidates for those who overturn the class 4 with an appeal. once a candidate has overturned the class 4 with an appeal they are usually given a class 2 which for them they need the ADF's medical senior medical officers to sign a waiver before the candidate can enlist.

Class 3 (Temporarily Unfit)

Class 3 is given to candidates and ADF personnel who are waiting for a surgery or who are recovering from one. this class means that you can join the ADF but once the surgery is done and after you have recovered.

Class 4 (Medically Unfit)

This class is given to candidates who have medical conditions that require ongoing medical check ups, daily medication or that show a high risk of making their condition worse under the intense physical and psychological stress of daily military service in the adf.[2]

Class 4.E (Every Job Exclusion (ADF Sub-Code)

Class 4E is an ADF sub-code this basically means that you cannot enlist into the ADF because of a disqualifying medical condition like these listed: Epilepsy, Type 1 Diabetes and Anaphylaxis (EpiPen dependent). This does still allow for the candidate to make an appeal but it is usally unlikely to succeed like a candidate whoe got a class 4 (Medically Unfit)

ADF Personal Medical Class

Class 2 (Medically Fit with Restrictions)

With this type of class 2 this is for current serving members in the ADF who end up being diagnosed with a disqulifying medical condition like PTSD and depression. This class means that the ADF Member is able to serve in the defence force but with restrictions this means that the ADF Member is deployable and will be locked to certain roles with in the ADF when on base and out in the field as listed below.

• Recruiting
  • Help recruite new cadidates and attend career expo's
• Chef
  • Cook for ADF personal out in the field
• Human Resources Administrator (HR Admin)
  • Manage critical administrative, financial, and personnel tasks.
• Logistics / Warehouse Coordinator
  • Manage the storage, and distribution of military equipment and supplies.
• Electronic Systems Technician
  • Inspect, maintain, and repair advanced military technology.
• Psychologist
  • Support the mental health, wellbeing, and operational effectiveness of defence personnel.

When you are given this class 2 (MEC 2) if serving in the ADF you can go back to a class 1 (MEC 1) by going through the ADF Medical Employment Classification Review (MECR). To be able to be successful the member must provide medical evidence from their treating medical officer stating that the injury or illness has been resolved. Then the chain of command will compete a AD523 Workplace Capacity Report, this proves that you are performing your regular duties / role without any limitations.[5] For the last thing that happens is that the medical employment classification review board (MECRB) will review the members documentation and will then make a decision weather to accept or decline.

Medical Conditions That Can Give You a Class 4

Below is a list of health conditions that get you a class 4 (medically unfit):

• ADHD (Attention Deficit Hyperactivity Disorder)
• Depression / Major Depressive Disorder
• Anxiety / Generalised Anxiety Disorder (GAD)
• Autism / Autism Spectrum Disorder (ASD)
• PTSD (Post-Traumatic Stress Disorder)
• Bipolar Disorder
• Anaphylaxis
• Asthma
• Type 1 and 2 Diabetes
• Epilepsy
• Extreme BMI (overweight or Underweight)

While this sounds unfair the ADF is immune to the Disability Discrimination Act 1992 as they require candidates not to be a safety risk to causing harm to both them and everyone else.

Class 4 and appeal process

What Medical Conditions allow you to make an appeal

while it feels like getting a medical class 4 it is not over. With everyone of those medical conditions candidates are allowed to write an appeal but doing this can be very challenging. bellow is a list of high to moderate appeal success rates.

High Success Rate

• ADHD
• Depression & Generalised Anxiety Disorder
• Asthma
• Extreme BMI

Moderate Success Rate

• Autism Spectrum Disorder
• Musculoskeletal Injuries

Very Low Success Rate

• Anaphylaxis (EpiPen dependent)
• Type 1 Diabetes
• Epilepsy

Even though wining an appeal tends to be hard and challenging it isn't impossible to win with the harder medical conditions to win an appeal for you just really need some heavy weighted medical reports from you doctors.

What To Include In An Appeal

To make the appeal letter as strong as it possibly can be you need to get an extensive report from a paediatrition if aged 16 and a half - 17 years of age or a psychiatrist if aged 18 and above. You will also likely be required to get a not from your GP (General Practitioner) but it usually not needed. But the ADF does prefer to have letter from an independent qulified civilian specialist over a regular family GP.

These ones are optional but it can help strengthen the appeal and make it a higher success it is best to include these if applicable.

• Letter from a sports team
• Letter from a cadet coordinator
• School / University transcripts
• Letter from your boss at work

as those ones can be minimal it is recommended to include at least 1-2 of these to maximize the best possible outcome of the appeal.

Cover Letter For The Appeal

With an appeal for that certain medical condition you are appealing for you are required to write a cover letter. In the cover letter you are essentially telling the adf what you are appealing for, that you don't agree with the adf's decision. In the appeal you also want to state all of the evidence to support you appeal so that's going back to like, school / University transcripts, a letter from you sport coach. For the little extra things that can't be missed is your name, candidate ID and what roles the candidate applied for. Once the appeal is done the candidate is to send it of to medreports_mel@adfcareers.gov.au

ADF Careers Medical Appeals Section Defence Force Recruiting

SUBJECT: Medical Appeal for Class 4 Classification – [Candidate Name] (candidate ID: [Insert ID])

To the ADF Medical Appeals Committee,

I am writing to formally appeal the Class 4 (Medically Unfit) classification received on [Date of Assessment] regarding my application for the role(s) of [Insert Job Roles, e.g., Infantry / Combat Engineer].

The initial classification was issued due to my history of [Name of Condition, e.g., ADHD / Asthma]. I believe I am fully capable of fulfilling the physical and psychological demands of ADF service without posing a risk to myself or others.

To support my appeal, I have enclosed comprehensive evidence demonstrating my current stability and functional capacity, including:

1. A formal specialist evaluation from [Specialist Name], confirming [key positive finding, e.g., complete remission / asymptomatic status off medication].

2. Academic transcripts demonstrating performance.

3. A reference letter from [Employer/Coach/Cadet Coordinator] highlighting my physical capabilities.

Thank you for reviewing my file and considering this additional evidence. I look forward to your decision.

Sincerely,

[Candidate Name]

Outcomes of an appeal

Once a candidate has sent off an appeal with an extensive report from a medical specialist there are usually long wait times for the adf's medical team to review the appeal that you made, the time it takes for them to view the appeal is 4-8 weeks it can even go up to 12 weeks depending on how busy they are at the time.

Accepted (Class 2)

If the appeal is to be accepted, in the ADF terms they will say overturned which means they have disregarded their original decision. After that you are usually given a class 2 (fit with waiver) but sometimes they can give a candidate a class 1

Rejected

If the appeal is to be rejected then the ADF will say that your appeal has been upheld (meaning you did not win the appeal), this means that you did not gather and submit good enough medical evidence. If you are to be upheld though don't worry too much as they will allow you to reapplly in 2 years from the date of the medical assessment.

Common Reasons Why Appeals Get Rejected

Understanding why the ADF Medical Appeals Section denies appeals can help candidates avoid critical mistakes. The most frequent reasons for rejection include:

• Insufficient Specialist Qualifications: Submitting a report from a General Practitioner (GP) or an under-qualified counselor instead of a certified civilian medical specialist or consultant psychiatrist.
• Lack of Unmedicated Stability: For conditions like ADHD, anxiety, or depression, the candidate has not been off medication or completely symptom-free for the ADF's mandatory minimum timeframe (often 12 to 24 months).
• Vague Specialist Language: Reports that use hesitant phrases like "the candidate should be fine" or "unlikely to cause issues" rather than definitive, evidence-backed statements certifying the candidate is fully stable and safe.
• Failure to Address Military Stressors: The specialist report evaluates the candidate's fitness for normal civilian life, but fails to address how they will cope under sleep deprivation, extreme physical exertion, and prolonged psychological stress.
• Missing Historic Medical Records: Failing to provide the full diagnostic history or childhood medical records that the ADF explicitly requested to track the progression of the condition.

How to Prepare for the Specialist Appointment

The independent specialist report is the single most important document in a candidate's appeal package. Candidates should take the following steps to ensure the appointment yields the best possible outcome:

• Obtain the Specific ADF Request Letter: Bring the formal rejection letter or the specific medical questionnaire provided by DFR, which details exactly what questions the ADF needs the specialist to answer.
• Compile a Complete Medical History: Gather all past pharmacy printouts, GP notes, and childhood reports regarding the condition so the specialist can easily verify timelines (e.g., exact dates of stopping medication).
• Provide a Copy of the Job Description: Show the specialist the physical and psychological requirements of the specific ADF roles applied for, so they can explicitly state you are fit for those duties.
• Be Fully Honest and Transparent: Specialists are trained to detect minimized symptoms; hiding past medical issues can ruin the credibility of the entire report if the ADF cross-references it with Medicare records.
• Request a Direct Final Conclusion: Politely ask the specialist to include a clear, unambiguous concluding statement in their letter confirming that the condition is fully resolved, stable, or asymptomatic.
