Hi David,
In older houses I've seen the jolly greens in toilets and showers. Its quite funny when someone is indisposed and a loud croak springs from underneath the seat.
I used to see the frogs around Townsville back in the '70s and Brisbane is as far south as I have seen them. Also I used to see hundreds of the smaller greenies after rain in North Qld. We have a few of the smaller variety here too. They seem to screech at times and are capable of very high and long leaps.
Cheers
