[talk-au] How to efficiently improve AU address coverage?

[Yuchen Pei]

Hello,

I read in a 6-year old post[1] that the Netherlands had an address
coverage of over 99%. This made me curious what would be the Australian
number. G-NAF boasts 15M addresses[2], whereas according to
metrics.improveosm.org there are less than 1.2M address points mapped in
AU[3], so that makes it less than 8%, way lower than the Netherlands.
But please correct me if my stats are flawed.

Is there a way to efficiently improve the address coverage in Australia?
What are the main roadblocks?

For Victoria there was an initiative to import vicmap addresses[4][5],
I wonder how many addresses it will add, and why it apparently got stuck
