We went for a trip to the Kaikorai Lagoon out by Waldronville (10 mins out of town) and explored the estuary environment. It was, quite frankly, pretty yucky. Apart from the smell of mud, which is not that bad, there was rubbish everywhere and the kids found a dead pig skeleton which was still pretty stinky. Andrew learned not to run out into mud and escaped losing his gumboots by the skin of his teeth. There was plenty of wildlife but it didn't come anywhere near us, so we didn't get to see the cygnets we've seen from the van - they seem to be shyer of people walking than vehicles driving past.
Daniel was busy for a while making lego ships which turned out pretty well.
