Money flowing out in the two routes you mentioned is peanuts compared to the money flowing in: finished goods being purchased in bulk at a lower price and then being sold at a higher price. Or alternately for foreign owned businesses, goods being manufactured remotely for very cheap, where Australians can employ near-slave labor and ignore environmental regulations and then said goods are brought home and sold very expensively relative to their production costs. In both cases, the owners of the corporation are able to take a large slice of the finished value of the goods despite them being made by others elsewhere.
