A border of Mondograss would look good, then a few natives scattered around. Dwalf and ground cover varieties are good as the won't block out the house. Grevillea Robyn Gordon is a beauty 1 mtr high and 1.5 to 2 across with red flowers most of the year. So to is the Tibouchina Joules a shorter flowering season but brilliant purple in autum, the rest of the year it is a compact green shrub to around 1 mtr. Banksia perhaps?
Maybe 1 taller shrub as a show piece in the middle or near the driveway?
Have a walk around the block and see what is growing well. Go to the local nursery, have a look around, ask there advice on what grows well in your area.
Mulch well, at least 75m/m thick, cypress pine is good as termites dont like it, or pebbles?
Depends what you like.
