Native plants for front of house.?
There are heaps of natives you could use best to check out bunnings or better yet your local nursery so you can see pictures of the plants and their flowers. Grevillea's such as 'honey gem' with orange flowers, or 'elegance' which has great light to deep pink flowers would work great. things like bottlebrushes (callistemons) come in a range of wild colours as well. Those suggestions are like really tall shrubs but you can keep them cut back to the size you want them, however other small shrubs which you might like are Westringea's which come in a range of blue/white small flowers and various different types of leaf colour.
Best bet though is to check out the nurseries or markets and look at the pictures on the tags.
I hope i was able to help and check those plants i mentioned,
