We are taking the Sunlander from Cairns to Brisbane. As of now, our plan is to stay one night in Brisbane and fly to Sydney the next morning. We will then have 2 1/2 days in Sydney (We will get there on a Thursday morning and we are leaving to go home on Sunday - no time to do anything on Sunday.) Is it even worth it for us to stay overnight in Brisbane? We were thinking of going right to the airport from the Sunlander and going straight to Sydney to have 3 full days. Opinions?
