@Purschy (and CC:@Tapirlord ) I like respecting your authorial identification, in that sense i ask if you've information available to confirm this identification _Toona_ciliata_ ;
contrasted with an alternative hypothesis i openly offer here as a test here towards confirming _Toona_ciliata_, based merely on what is visible in this single photograph, of thus visually plausibly: _Dysoxylum_fraserianum_ ?
Does this tree have deciduousness –loosing all its leaves in a harsh season? A simplest example way, to rule out _Dysoxylum_fraserianum_ . Quite usual for _Toona_ciliata_ to loose all its leaves in a harsh season. Quite unusual for _Dysoxylum_fraserianum_ to loose all its leaves, even in a harsh season.
Hi, thank you for that thoughtful comment. There is Dysoxylon fraseranum nearby, but I can confirm that one is Toona ciliata. Sorry it isn't a super clear photo but I know that tree is one of a very few that was planted in this regeneration area, almost all the rest of the area, and the rest of the property, we are managing with natural regeneration techniques. Apologies again for not specifying that - I realise now I neglected to hit the "planted" button when I uploaded. There are also a couple of fairly large (about 20 metres) naturally occurring red cedars further down the valley, and probably hundreds of seedlings coming up, possibly triggered by a fire that came through in Black Summer, I think on 13/11/2019.
