I definitely don't have anything resembling thermal underwear, or flying gloves...hope it won't be too cold.
You're kidding aren't you ? You hope it won't be too cold !?
Are you 'Gen-Y' by chance !?
Have you considered what might happen if you actually do get selected for training as a PLT in the ADF ? Here's a tip: no matter what your position (Category/Mustering) - there's an expectation that crews and equipment will operate and deploy (for sustained periods) under wide ranging temperatures and weather conditions. Yes, that means you may get cold (and wet) and you will have to sort your own clothing needs, appropriate to the predicted climate ... all this by yourself !!
If your intention is to join RAAF, then I hope you enjoy Exercises' Labuan and Tarakan whilst at OTS. Especially during the less warmer months in Sale !!
If you're accepted for Army SSO, then it won't be so bad.
If you don't have anything resembling "thermal underwear" - maybe go and buy some ! Better still: use your initiative (and on-line resources) & perhaps consider checking out the long range weather forecasts for YSTW on the internet - that may give you idea if it's going to be cold or not !!?
Here's another tip: you're being assessed at FSP for 'Commissioning Potential' as well as an ability to learn at a certain rate in the air environment. The rest is up to you.
Good luck.
