There are Indonesian White's Tree Frogs, and Australian White's Tree Frogs. Some of the more noticeable differences between them is that the Indonesian ones are often a pea green color ranging down to brown, and are typically available as imported, wild caught subadult to adult frogs. Australian White's Tree Frogs are always captive bred, and often have a blue or teal hue to them, especially as they get older.
I believe in Australia, they just call White's Tree Frogs "green tree frogs". This may also apply to White Lipped Frogs, which are related to White's Tree Frogs but are NOT White's Tree Frogs.
White's Tree Frogs (both kinds) are often referred to as "Dumpy Frogs" as well, or as "Buddha Frogs". These are simply common names, often referencing their pudgy appearance.
America also has green tree frogs, but ours are much smaller, and do not take as well to handling.
The racing stripe *sounds* like it is probably a white lipped, but without seeing them it is hard to be 100% sure. The lines are not a usual marking for White's Tree Frogs/Dumpy Frogs, though.
Lastly, check the latin name.That will always be the most accurate name to go by.
Hope that helps!
