Pizza all around the world comes in various shapes and forms. Each region of the world has its own variation of pizza and how its made. The common type of Australian pizza is called the Aussie, Australian or the Australiana and has ingredients such as tomato sauce and mozzarella cheese (which are very common in pizza) and bacon and egg (which are uncommon for pizza). Pizza with seafood such as prawns are also popular in Australia. Australia also makes ''gourmet pizzas'' with salmon, dill and tiger prawns.
