it’s a cool city, quite a bit to do but like the rest of Oz it’s very expensive when it comes to beers/ food and some entertainment in fact most things are due to exchage rate.
It was a couple of years back, but I found nice wine was good and cheap at least if you drink Australian wine, and they do make some jolly nice ones. Restaurant dinners not that expensive compared to London, and the same thing where if you find reviews and take public transport a bit out, you can find some very high quality inexpensive food. Cafes, lunches, snacks were eye wateringly expensive at times though, odd things like chocolate bars and ice creams were real wallet rapers.
What a nice city though, nice biking nearby too. Oh and kangaroos are brilliant. I saw them in the wild in the You Yangs, really bizarre they are. If there is any way you can engineer seeing kangaroos out in the country somewhere, just by coincidence, I imagine your kids will love you.
