There are lots of street numbers around parts of Brisbane (probably some of the most comprehensive are around Fairfield to South Brisbane). It's pretty easy to add - I traced my neighborhood and added address data in a couple of hours.

If you want to make the world a better place, you could do some around your house as well!

I certainly could - and might - but the lack of such information is why OSM s still not a viable replacement for commercial maps. (Yet).
