I buy refills for Brother printers from these guys and I find their service and quality to be excellent, and now everything is on sale at 10%-15% off until 20 December. Their range covers quite an extensive number of manufacturers and models of printers and toners.
If you need full cartridges or imaging drums instead then they can usually supply those, too, but buying the refills in bulk is often better value for money, plus it's less plastic that ends up going to landfill.
Here's a sample of consumables for a couple of printers popular with Oz Bargainers.
