we went to a national park called 'Yanchep', which had a lagoon on the sea, and an inland park with wild kangaroo's and koalas etc.
we met at the lagoon with the other family (other uncle's family, and my brother and his girlfriend) and spent the morning snorkeling and swimming. the snorkelling wasn't great but it was red hot so nice to be in the water.
the afternoon was in the inland park, stalking the kangaroo's and looking at the koalas. we played a bit of footie, and cooked in the heat!!
