Right - they have very little in expenses in Australia. Because all the development and maintenance is in other countries. That is my entire point. So they take the market value (transfer price) of the expenses and transfer that money to countries where those expenses are incurred. They then pay for expenses related to their local offices and 2000 employees. What's left over is called profit, is taxed in Australia, and they paid $100mil of taxes on that profit last year.

Lets say you are sitting in Chicago. You create a search engine, get a thousand developers working on it. You then set up an Australian portal for that web page, on which Australian businesses buy ads. In your version, the costs for Australia are zero. In reality, those costs include the development of the search engine in Chicago.
