Is this a good breakfast? Only answer if u r from Australia cuz Australians r the only ones who no the cereal.?

I only like saltana bran crunch for breakfast, and only want that, i have a healthy diet...(vegetables, fruit, dairy, water, variety) but i want to know how much is right for breakfast, should i have only a little bit if i am on a diet or should i have about 2-3 cups.
