Our Aussie friends gave you a lot of good leads. There might be a few others there worth looking for as well. There are a couple of Artocarpus relatives: Parartacarpus venenosus and Prainea limpato (not sure if this is the same ssp as the Bornean limpato with the wild shape). There are several Baccaurea with at least two mentioned as valued for the fruits: carinata & papuana. Mangifera minor is supposed to be fairly common; it sounds like it as a nice sweet-sour taste when ripe but is quite fibrous (also much more wet-tolerant than indica). There are some ginger fruits like Hornstedtias available there. We had a forum member there who had reported on a Tegtrastigma sp. (similar to a grape) with fruits of nearly 2" and flavor similar to a grape but a bit more sour. And there are nuts, besides the Terminalias that Mike mentioned, there are also various Canariums & Barringtonia.
