Thanks everyone so much for your suggestions. The general consensus seems to be that we should work on the garden, which we agree with and this is actually what we are in the process of doing. Love bcdc602 suggestion of adding silver leaf plants and grasses. We recently planted two lilly pillies either side of the front window which will grow quite tall and cover those solid brown sections of wall. We are also removing the blue awnings over the coming weeks. Interesting suggestion by telperien to paint the window frames white. Will give that some thought. Thanks again!

Plant Eucalpyts at your peril and have fun getting things to grow under them. Low maintenance? Northern Tassie yeah? Retaining wall across the front set back 1m from front boundary with a return either side(height? I don't know your levels but 1 to 1.2m is always a good height and needs no engineering detail). Scoria or white pepple, multi coloured stone between nature strip and base of wall. Above retaining wall a mass planting of succulents amongst another stone bed with some semi mature shrubs that grow well in your locality. Wide as you like it in regards to the garden bed above the wall with stepping stone(big paver, non invasive ground covers in confined squares ect) access to it and through it. One specimen tree in centre of garden(no...not a gumtree. Got a farm? Yes? Then you can plant a gumtree). Various really large pots with specimen plants in them placed up near your front entrance. A detailed plan could be done with much more info but you'll have to contact a local landscaper for that.(and plant advice and try to get an idea of where you plant/tree choices will be in 10 years even your not there) .

This is what we are working with. I'm slowly painting the colourbond "domino" and wanting it too look much more fuller with plants but not sure what to do. We need some screening from our neighbours too. Thanks

Sydney is out of my comfort zone for plant naming. I would still use the line of trees on RHS of driveway. I would clear the area on the left also. Consider tall trees towards the front of your property with open crowns. Double storied homes need tree height to provide balance. Closer to home maybe one or 2 smaller deciduous trees to give shade in summer. Retain the LHS of driveway with large embedded rocks. Maybe only native Lomandra with only 1 variety in pockets in the rocks. Very simple concept, but I believe will add real value to a good home. Please bear in mind that this advice is from a photo only.
