Tricky ID unless you are familiar with Australian flora. The bark of the tree is very smooth (not much of a clue I know) and apologies for poor quality of photos. But thanks in advance for any ideas!

Looks like a lagerstoemia indica (crape myrtle) :o)

I think it's lagerstroemia indica, frost hardy, just. Deciduous. Wants a very sheltered spot

Great minds . . . !

'Twas the bark that convinced me. I put it into 'my pictures' and blew it up. Lovely smooth bark that flakes away in patches so you get different shades.

Thanks Bulba, but the pink flower is growing on the tree. We saw many Eucalyptus in Oz, mostly with long, narrow leaves (saw a Koala eating one too!). Blog soon.
Thank you Plantoholic . . . I hadn't heard of lagerstoemia indica, though crape myrtle rings a bell.
Thank you too, Worthy . . . I'm amazed. And grateful :))

Assuming that the pink flower is a seperate plant, I would have thought that it was an Eucalyptus.
