Kiwi fruit will grow in most of temperate Australia - and with careful placement even in areas that seem unlikely.
Fruit should appear after 2 - 3 years; some authorities recommend picking before frosts, but I find that frosts tenderise and sweeten them. Don't wait for the fruit to get ripe on the vine though - it doesn't. Pick and wait for anywhere from three days to two weeks for them to ripen indoors. The riper they are, the sooner they'll soften inside. If they don't taste sweet, they aren't ripe enough to pick and if they leave a furry taste on your tongue, they are definitely not ready. Note: Your home-grown fruit will be MUCH sweeter than shop bought stuff; and will have more flavour too - commercial kiwi fruit never seem to have much flavour at all, just vague sweetness and a hint of scent.
