Hi Allen! There are a few things you need to ask yourself before choosing and planting a tree, such as, will it grow too big and block the view from my window, will it drop messy leaves or fruits onto my lawn or driveway, will it require a lot of pruning, and will the wildlife eat it. I'm not familiar with Australian tree varieties, so I can't give you specific advice, but if you look around your neighbourhood and see what other people have in their front gardens it will give you some clues as to what to plant or not to plant in front of your house.
