Hi @Former-Member, mine's going fairly well. I've concentrated on planting things that are dry tolerant, so most of it copes without watering, even in summer. There's a pear tree and a persimmon tree that I keep an eye on because they're relatively recent plantings and still need to get their roots down deeper. Otherwise it's mostly the pots and the tomatoes that I need to watch. I have lost a few young potted plants, and a few native shrubs that the wallabies had snacked on succumbed as well. The double whammy was too much for them.
I've stolen some inspiration from Lambley Nursery's "Dry Garden" (photo) and other low water gardens. There's quite a lot of species that need little or no water and still manage to look good. Sedums, agastaches, salvias (some of them anyway), phlomis, some lavenders, senecios, artemisias, achilleas, yuccas. Then you add in natives and succulents, plus bulbs and annual flowers that have their active grwoing time when the weather's coller and damper, and you've got a pretty good range to choose from.
