Silke I think this is Pomaderris betulina subs. actensis, which is endemic to the ACT and nearby NSW. The leaf margins don't appear to be downturned i.e. folding under, which is a distinctive feature of subs betulina can you please check
Hi Michael, here are some more photos. After looking at the PlantNET website I'm tending a bit more towards P. betulina subsp betulina, mainly because of the deeply impressed secondary veins. What do you think?
