In about 7 weeks I'll be headed to Melbourne for about 10 weeks, 8 of which must be spent in Melbourne and the rest I have free. I'll be working for the Australian Bureau of Statistics, so I get weekends off. So between weekends and time off, what should I definitely do? We were thinking of going to Sydney for a few days, and a possible trip to New Zealand or up north to the Great Barrier Reef. Any suggestions?
