I have seen it in northern nsw reaching a height of 8m.
It would be a rather benign exotic to plant, it has a bushy upright growth habit. Im not sure if it would like full sun as the one I saw was in the shade, fruiting like crazy I might add.

Thanks for that - exactly the information I was looking for. Did you see it at Tropical Fruit World by any chance?

Nah,
I saw it at a friends place near Byron Bay, grows exceptionally well down there.
