We found these in a mostly dry muddy swamp. They were very hard to photograph, because they wouldn’t stay in one place for more than a few seconds, and after hopping they would blend in with the dark background nearly perfectly.

There's at least one other candidate species of Crinia in the area, Crinia bilingua. C. remota is the smaller of the two, but C. bilingua is quite small also, and it's possible that the ones I saw were not fully grown in any case. Please let me know if you know more about how to distinguish these two species, other than by call (since I did not hear any calls).

I’ve written up an account of this three-week trip to Australia here.
