with the native trees next door i'm wondering what you mean by formal?? some native shrubs like like correas or westringia or big strappy plants like dietes, lomandra, dianella can be made into a formal looking garden but check with your local nursery to select most suitable plants for your local climate and make sure you prepare the beds and watering system before buying any plants
Lilly Pilly is an Australian native that come in a number of varieties of heights, leaf sizes, leaf colours and flower colours. They can be trimmed quiet formally.
