It certainly does look like Cassia fistula. I had no idea it grew way down there.
Hi Bernie,I have seen a few around Sydney. They are common around Asian temples here. I was surprised but our climate is pretty similar to Brisbane, just a couple of degrees cooler and rain all year rather than wet - summer/dry winter. So if they do well there, the coastal areas of Sydney should be OK. They are such a nice tree.
I love cassia fistula, and i think you are right.
They are so unique in how their flowers hang down..a little yellow chandelier!
We have this trees too and its really spectacular when in bloom. It does look like Cassia fistula.
It's very pretty
