Just to update here, my seedlings are growing really well here in SE Qld, they actually seem to prefer the cold weather of autumn/winter, not surprising considering where i collected the seed on the Atherton Tableland it was really quite windy and cold every time i went there

They always prefer the mountainous areas, probably just die to the temperatures maybe, even in PNG, but i guess it's warmer over there overall. Will get some more pics in shortly.
Propagation is still in trials, nothing really to report yet.
