A lot of companies offer postgraduate scholarships for you to do research in a specific field, eg - the dairy association might pay you to research milk production. Mostly its in the form of like a $25,000 or so tax free stipend per year. Usually for research that the government matches the amount of money put in by the corportation in exchange for making any discoveries available to everyone, not just that specific corporation.
I know sydney uni entomology dept offers a scholarship to anyone willing to spend a year researching cockroaches, and they've had trouble offloading it...
you can also get PELS, but i'm not sure how that is changing next year.
