I'm a little north of "The Bay".
Between Sydney and Bega the conditions are very similar, possibly seasons lag a week or two further south.
Back in 1972 when national service finished I hit the road on my trusty CB750 and spent a winter in FNQ, loved it!
Wife and I have been to Tas twice and were planning on moving full time until the grand-kids started arriving.
Bottom line ... you acclimatize as long as you have a positive attitude, and I'm positive FNQ is too hot in summer and Tas is too cold in winter :-)
