The food here in Australia is similar to California. They call their meals breakfast (or brekkie, because Australians love nicknames), lunch, and tea (this is their dinner). They eat pancakes, bacon and eggs, or cereal (called muesli) for brekkie; sandwiches and salads for lunch; and roasts, barbeque, pasta or fish for tea.
The most typical Australian food is barbeque. Barbeques are found everywhere: at home, on the beach, or in parks. They barbeque steaks, chops, sausages (called bangers), fish, or vegetables. This is where the famous line by Paul Hogan, who starred in the movie Crocodile Dundee, comes from. In a television advertisement to encourage tourists to come to Australia, he says, "I'll slip an extra shrimp on the barbie for you." Some of the shrimp (called prawns) are really as big as the one in his hand and they are delicious.
Another typical food is meat pies which are eaten for lunch. Meat pies are small pies with meat, vegetables and gravy inside. This is what they look like.
One other food that is popular here is vegemite. It is a dark, salty paste made from yeast that they spread on buttered bread. They eat it for breakfast, lunch or snacks, like people in California would use peanut butter. Children here like it, but it has a strong taste and can be an acquired taste for non-Australians.
Good on ya, mates, and keep your questions coming.
