Sorry for long time to reply, I have been offline. To answer the question I will be in Melbourne on 23Sept and leave Cairns on the 10Nov, so let me know what you think?
Thanks
Queensland has stingers in some areas over summer so you want to avoid northern queensland from about Nov to April. If I was you, I'd start in Cairns and go to Melbourne, Cairns will be better in September and by the time you get to Melbourne it would have warmed up with sea breezes.
