I need advice whilst planning a trip to Australia in the Summer. We can only go for 3 weeks cos of other half's holiday - and we want to go to Bali for a few days on the way back. The way flights are - we can arrive in Cairns on a Wed morning and stay there until the Sunday when we fly to Sydney until the Thursday and then fly to Melbourne until the Tuesday then fly home. Other half thinks we should spend longer in Sydney. Neither of us has ever been to Australia before so would appreciate any advice! Do those days sound decent enough? Should we move anything about?
