In the foreground I think these are Agile wallabies. On the opposite edge of the waterbody is a feral pig (the black blob). These animals are a real pest to Australian water ways, Our animals dont have hoofs and becasue of this they dont compress the soil as much. Our plants (lots of the grasses) have evolved in soil that is open. not fouled up and compressed by pigs wallowing in it. All the edge vegetation is destroyed by them. So they have little chance once pigs move in. They are increasing in numbers and seem to be less afraid of people than they use to be, In the two months I was away I saw around 30 of them. Some from much closer than anyone would want to be. I use to think in Australia that we were lucky becasue we dont have bears or lions to worry about when we camp (just deadly snakes and spiders :) ) But the tusks of pigs look huge and because I sneak around taking photos I have surprised a few of them when I have been down wind from them. A family of pigs running by you is terrrifying! worse than any snake or spider.
This is another shot taken at Karumba. Egrets in the foreground and a flock of darters in the background drying off. Also below.
