lol we'd be tucked up safetly in bed come nighttime!
in which case there's the Aquarium. Warmer than a beach in the middle of Winter and they have penguins. The kids are probably too small for the old melbourne gaol. It creeps me out but I'm a sook. There's the childrens garden at botanic gardens or Scienceworks. Or the childrens farm at Abbotsford convent. Or boating at Studley park.
