Thanks for the info!

I'd agree with you there, & that is how I think all GC "localities" are
mapped. Not all suburbs yet have their boundaries mapped though (although
the separate PSMA discussion may achieve that?)

I have mapped boundaries in NSW and SA and I think LGA at level 6 and

No, I agree no real overwhelming reason to change. It was just a thought
seeing that level 9 isn't used.
