I regularly compare Melbourne's weather to the Mediterranean. @Fosh - in my garden I grow olives, lemons, limes, oranges, grapes and mandarins very successfully. My wife planted some plants with massive leaves (cant remember what they are called) that cannot tolerate frost, they have prospered so that in 5 years since planting they are really too big. With very hot summers and hot autumns, where sometimes it doesn't rain at all for weeks on end, the fruit trees that are traditionally Mediterranean thrive, although you do need to keep them well watered! Winter is cooler, even then many days can be sunny in the high teens and it never gets "hats and gloves" cold. Please don't be put off by comments about the weather, you'll be fine here!
