We may as well have a thread keeping track of all retirements instead of starting threads for each player. So far Milos Ninkovic, Leigh Broxham and Jason Hoffman will be hanging up the boots.

All the best lads.

Does moving to NST count as Retiring ?

No, I don't think so.
All information so far indicates the Australian Championship (NST) will be a fully professional league, so a player couldn't really be both retired and have a pro contract with a Championship club.
It's essentially the modal scope fallacy (eg: you cannot be a married bachelor).
