Welcome to the forum, Sue! I am more familiar with trees here in Texas, and unfortunately we don't have the lovely tree you posted a picture of, but here is a site that may help you identify your trees:

There are differing opinions about global warming, but I did see a polar bear holding up a "Homeless" sign
!
I like your sense of humour would a sight to see a polar bear holding a sign huh guess it would be too hot for it down under so we have Taniwha that live in the water.
No help for the trees but yes I have an awful problem with the vegetation around my home they grow like crazy and I'm forever having to prune them. Also the wild life (opossum) are a pest too.
My lemons are all disappearing or rather they are still hanging on the tree minus their skins...
I watched a video on how to grow trees from cuttings and taken some cuttings of this tree and several others but at the moment it's not looking too promising but will try again later as it might be the wrong time of year to do the cuttings.
Watch out for those polar bears!!!!
