Thanks guys for the info.
We had a good weekend, however did find the place a bit boring and the locals really unfriendly as opposed to Leeman or Jurien, but we had a good time kicking back, swimming, and fishing nonetheless.
Didn't do much offroading (mine was the only 4x4 there), but did go from Stockyard Gully Caves to Lake Indoon via the 4wd track. But that's as hardcore as we got. When we arrived at Lake Indoon, we were greeted by a sign that said , "Beware, swimming in the lake may cause amoeba meningitis" or something like that. So we thought it might not be a good idea.
I spoke with a local in the Leeman servo, and he reckons we were mad doing the 4x4 track and the caves in 40 degree heat... and that Lake Indoon is safe to swim in...
