I do not see details....but reminds me of Delonix regia

Ah, thank you! I originally searched the net for "red flowering trees in Brisbane" and Delonix regia was a popular hit, but the trunk and branch structure didn't really match the pictures that were appearing.

However, as soon as I searched for "Delonix regia" as per your suggestion, the first picture that appeared was basically a direct match for the one I posted.

Thanks again, bromelia2010 - greatly appreciated.

Yes, and commonly called Poinciana here. Also very commonly used in street plantings in the older parts of Bris. Along with Jacarandas. Caused huge damage to footpaths and roads but what a glorious sight in an avenue of them in bloom.
