The only tree I quickly recognized on my first trip DownUnder was Sycamore. It’s the only tree native to Oz and this part of the US. Got a few of ‘en in my yard.Na totally different tree. I'm pretty certain their not native to Australia but they grow like a weed through the bush here in Queensland id guess also down through NSW. They grown a huge sprawling canopy and shade out the undergrowth so nothing grows under them.
They also grow along our creek systems.
They are great big trees but they arnt good for our native vegetation.
No mosquitoes under a camphor tree their sap is a natural insect repellent.
