Is there any other tips on things I can do so I don't lose all the skills I have learnt so far?
First of all congrats on the solo! Have imaginery conversations with yourself and ATC. I don't know what the score is in Oz regarding RT but just have a departure conversation or a zone crossing conversation with yourself while cracking a tinny.
By the way, I go to Bris every year for a month and looked into doing a conversion over there so I could rent a plane when on holiday. That was until I found out the cost...jeez you guys pay top dollar for flying, I'll never complain about the cost of flying in the UK again. I tried Archerfield and Redcliffe, where do you fly from?
