The fence will end up being a modern picket fence, We aren't sure if we should grass the two squares or plant it out, it's a nice sunny spot, but we have nosey neighbours that we are trying to make disappear, if then it becomes more private then a seated area could be really nice, Hopefully the right plants will work or we will have to go with plan B, of installing barbed wire and two wild Dobermans!

Wow! What a beautiful home :-) It's got lovely clean lines, but these can also look a bit stark, can't they? Have you considered Espalier or something similar against the walls between the garage doors, etc.? That would add some softness and colour (as well as fresh fruit!). For the front garden, you've really got a lot of choice for such a lovely aspect. If you were after a more 'finished' look, then perhaps consider a front (picket) fence with smaller natives and a bigger grevillea or similar as a feature. For privacy, perhaps a hedge of lillypilly. Or for a more formal look, landscape with sandstone to create tiered beds and plant out with smaller natives, lavender a herb garden or a mixture of all three. Enjoy!

I read an interesting comment somewhere, where a lady invited a group of her friends over to lovingly point out all the problems they saw (through fresh eyes) with her home on preparation for sale. She said she was surprised at marks and damage that she had lived with for so long she no longer noticed them. We "owner built" a home previously, and when we came to sell 7 years later, we painted the garage and did those jobs that we had put off, and it became sad to finally see her at her best, at the end, when we could have been living in a completely finished home all that time. I read about a lady who decluttered her home, had it professionally cleaned (build clean, or bond clean) and had a professional styler do her home and she realised just how nice it could be and decided not to sell. :) ta

We have very similar narrow side gardens. Judging from your picture, I'm guessing that you get more sun on the left. So, close to the door you could have pots of varying sizes and similar colour with dark leaf cannas and contrasting agaves potted, which won't overtake your garden because of the pot restriction. On the shade side, I'd plant ferns at intervals with clivia inbetween. You could also put up some chicken wire on the fence and train jasmine. On the sunny side, cordyline show-off, vireya rhodos, hibiscus (beautiful varieties) and bromeliads for groundcover. Good luck and have fun.
