But of course there are dishes which can be considered as typical Australian food. People eat a lot of red meat, especially beef. And no wonder, as the beef in this country is among the best in the world. Lamb is also a favourite food and so is pork. Chicken and fish are very important in Australian diet.
Traditional Indigenous people ate foods that they were able to find on the land, as they did not have shops or supermarkets like we do today. The types of foods available depended greatly on the group's location in Australia (desert or coastal areas) and on the seasons (summer, autumn, winter, spring).
