The Italians and Greeks have had a great influence on Aussie cuisine since the 1950's when many migrated here after WW2. Then in the 70's the Vietnamese arrived and showed us yet another delicious cuisine, and different vegetables and flavourings. ie Bok Choy, lemon grass. The Chinese also have influenced what we eat and dragon fruit is available in the fruit shops. Our recent migrants are from Africa and I'm sure they will also teach us about different foods too. Halal food also will soon begin to become more common as more people from Muslem countries arrive in Australia.
