Help needed with Eucalyptus photos

A DG member has asked for help with photos of Australian trees for an upcoming article. Some I may be able to get at the botanical gardens here in Sydney, but doubt I'll find all of them. They come from all over Australia, so I am asking for help from anyone who has the time & inclination to photograph gum trees. The article is being written by LariAnn & looks quite interesting. The trees she wants are:

Corymbia citriodora - Lemon-scented Gum (Qld)
Corymbia ficifolia - Red-flowering Gum (WA)
Eucalyptus nicholii - Narrow-leafed Peppermint (northern NSW)
Eucalyptus robusta - Swamp Mahogany (NSW)
Eucalyptus globulus - Southern Blue Gum (Vic)
Eucalyptus preissiana - Bell-fruited Mallee (WA)
Eucalyptus cinerea - Argyle Apple (NSW)
Eucalyptus phoenicea - Scarlet Gum (NT)
Eucalyptus leucoxylon - Yellow Gum (Vic & SA)
Eucalyptus forrestiana - Fuschia Gum (WA)

The states listed are where each tree originates but many can be found all over. If you have or know where to find any of these trees & are willing to help, pls post about it. Thanx in advance for any help.
