Ciaran @Tapirlord . Good arvo ! The location looks way off for this species and this sign on a walking track, at the moment located way up in the hills–mountain range in Dedin place name area.
I will look into this identification with fresh eyes.
Meanwhile please again find this individual tree, photograph again the key features and add another sighting.
During this spring season, hopefully flowering occurs which you can see and photograph. Then we can re-check the evidences for and confirm the identification .
