Hardy plants for my garden beds?

hi, i have just put in a heap of sleepers to make garden beds in my new garden. i live in victoria and have lots of frosts and are on the highest water restrictions (no watering of garden at all). i need some ideas on hardy hardy plants for about 100metres of garden beds. i am thinking daisies, diosmas, rosemary, jasmine, geraniums. any other ideas? thanks so much for any suggestions.
