Andrew, Thank you for all the hard work and achieving this key element. I would like to look at all level numbers to standardise these and to go forward. Also happy to have a dabble of the import process and associated doco.
I would like to aski if it is possible to 1. add the ability to have, possibly at [*5*], the Aboriginal nations e.g. https://commons.wikimedia.org/wiki/File:Map_Victoria_Aboriginal_tribes_(colourmap).jpg and 2. swap *6 Local Government Area (eg Shire/Council) *and *7 District or Region (e.g Perthshire, Fitzroy, Canning, Greater Sydney, Greater Melbourne, etc.) *as normally these areas are large than a singular LGA.
