Gday mate.
Given that they occur all up the east cost from around Brissie into SE Vic, iwould say that there care would be pretty much the same as Green Tree Frogs.
For the tank set up, make sure there are perches for climbing and to get nice and close to the uv light. Substrate is pretty much up to you. I always attempt to replicate my frogs natural environment as close as possible. For my frogs i use tropical plantation soil topped with washed river pebbles. Not 100% natural but good for plant growth and humidity levels.
As for food, crix, woodies and flies are always good. Just remember to dust with calcium powder every few feeds.
For temps, the best way to heat a frog tank is to use an aquarium filter in the water and a uv tube above the tank. (make sure you use fiberglass / plastic mesh for the lid) The uv tube gives off minimal heat, but the frogs will usually sit rightup the top of te tank to soak up the sun, so they do get some heat from it. The water heater set at 26-28 deg should be fine. Will give a nice humidity level as well.
Pricing is a interesting one. I have never sen these guys up for sale. If the boss wants a small green frog you could always go for either
Litoria gracilenta - Dainty Green Tree Frog
Litoria chloris - Red Eyed Tree Frog
oth of wich come up for sale reasonably frequently.
Cheers
