Hey mate, I work FIFO too so understand that its not just a one off trip.
I know there are lots of guys here on the gear, pretty obvious to tell. We fly Qantas too. I am not sure if they are just risking it or have other ways of getting it up.
My first cycle was through a clinic, and though shut down beginning this year, I only brought up prescription test, deca, var, arimidex.
Unfortunately no clinics are doing that this year as there was a major crackdown.
Safest course of action would be keep the jabs at home if youre on 1&1.
I have had my suitcase opened before and certain they went through my supplements as brand new supps had the seals broken, probably for swabs (i bring a few supps with me each swing). Only when I flew qantas though. smaller airlines with their private terminals (maroomba) was essentially jumping on a bus.
if your swing is longer than 1&1 then I have read some use longer esters, but I think getting a trt for at least test e would be a start.
shoot me a private message if you want to know more.
