Prevention is better than cure of course. But the answer is not to get rid of all your ponds, it is to ensure that they are deep enough for mozzie predators to enjoy.
1. avoid having rain water site around in little pools, make sure the water is stored in deeper containers where frogs can jump in (but not drown) and dragon fly can lay their larvae and eat the mozzies.
2. keep all the openings in your home screened, either with screen doors (these are cheap at recycle centres and often just need a clean and some new fly-wire). Fly wire can also save your home from sparks from a wildfire.
3. make mossie traps which contain yeast
4. some people nibble tiny amounts of bracken fern to repel mosquitoes
