One was a little sick looking but the others were ok. Hardly any nuts on them - only just on the top. The bark was unusual looking. Not seen these gums before.
Noted it was planted, which can make id of non-local species difficult. Features that point to Corymbia eximia (Yellow Bloodwood) : flaky yellow brown bark, barrel to urn shaped fruit, long petiole, often planted as an ornamental due to the masses of flowers at the ends of the branches.
