A am having second thoughts here. While the leaves appear to be either Dendrocnide or Gmelina, the lack of stinging hairs appear to favour the latter. There is nothing that beats seeking the plants live.
@Plants - thanks again - yes, I am still a little uncertain. I plan on visiting the known Gmelina at Minamurra rainforest tomorrow, before returning to take another look. I would like to see the trunk of a known example to help to decide.
