Up north there are beautiful trees with salmon pink trunks. I haven't been able to identify them, but I searched on 'salmon gum' and lo and behold there is such a thing!
Perhaps it is this: Salmon Gums (Eucalyptus salmonophloia).
The trunks are beautiful but I doubt that they're Salmon gums, because they generally grow in the south west of WA (not even as far north as Geraldton).
