Koolivoo Waterhole ?
There is nothing there but it is very peacfull. There has been built two bird hides to watch the birds and such. When we stopped there after the rains 2010 it was teaming with life in the extensive water holes around there.
I don't think that this is the name of the creek crossing that the camp is on but Lake Koolivoo is to the left of the highway and Lake Machattie is to the right.
The creek name is Eyre Creek!
