Thread drift for clarification:
The ADF does have reasonably high fitness standards. The initial test is fairly easy but expectations (at least in the Army) increase as you progress through your training and are posted to your first unit.
There is a readyness standard (AIRN) that must be met annually and part of this is a basic fitness test appropriate to age. People who have been injured during their ADF service are usually granted a waiver from parts of this test that they are unable to complete, but the emphasis remains on rehabilitation.
Unfortunately, people who have allowed their lifestyle to ruin their health (too much KFC) have also managed to be granted waivers and seem never to recover
. One member of my former Sqn failed his fitness test and was not allowed to deploy to Timor on my rotation as a private, gained a waiver, was promoted and deployed to the MEAO as a corporal. The same person is now a WO2 and has not passed the fitness test in ten years!
End thread drift.
