Thanks for the great info and advice georgo, can't ever have too much of that! Looks like the odds are stacked in favour of me having a bit of a wait (I'm anticipating one of the mid-Jan courses, but as we all know there could be complications that need to be sorted between now and then that could set me back a few months), but in the meantime I'll be making sure my angles are covered. I haven't yet been locked in for Assessment day (its a few weeks away), but I've been studying all the info I could get my hands on from my school days until now in anticipation for this, so hopefully I can make a good impression there and slot into FSP soon thereafter!
Good luck with OTS, perhaps I'll see you in the RAAF in the coming years
