Welcome,
Canberra is cold in winter and big fat roads (careful of black ice - this is a layer of ice on the road which cannot be seen very well, hence slippery) and A lot of round-a-bouts so get some coilovers and strut bars to enjoy it!
Also, Canberra went through a huge cull in the public service (I am one of them), so people finding work is pretty competitive. However, your line of work probably wouldn't be that affected hopefully.
one more thing, every Friday night the Silva and Skyline boys and galz meet up at Grevillea park (right next to the CBD - the big lake) from 9:30pm until you want to leave (12am'sih). They just talk cars and politics
Other than that, welcome.
