You can get both light and normal varieties everywhere. Desserts Australia is a cake and torte country. Don't expect to find great apple or blueberry pies here. But you will find great looking cakes with lots of cream. Check out Manuka when you are in Canberra and Bondi when in Sydney to see what I mean.
Pavlova is a national treasure.
It is made of egg whites and sugar, meringue, topped with cream and fresh fruit. Carrot cake can be found everywhere. Bagels Don't expect New York type bagels here. Australian bagel's are lets say Australian bagels. Australia is a big beef producer.
