They have kept their research division alive. And they actually do a lot of research, as opposed to mooching from universities or refining what competitors do.

Why here? It may be the case that Australia's R&D tax incentive plays part of this [2]. Or perhaps it could be that Australia produces a decent crop of well-educated researchers, while much of the economy is based around extracting natural resources and selling them, so there isn't too much competition for employees.

[3] i may be completely wrong about this.
Also note that not all patents come from their Research division; anyone can file for one.
