Hi Esther,
Love your list of internet service providers in Australia although I noticed that you have not listed Aussie Broadband or Wideband.
Aussie Broadband are one of the only ISPs (outside of the big 4) that are building their own connection to all the 121 nbn POIs around Australia.
Their domain names are:
https://www.aussiebroadband.com.au/
http://www.wideband.net.au/
Here are a few of their recent features from major media outlets:

You can read more about their POI rollout here: https://www.aussiebroadband.com.au/blog/aussie-broadbands-poi-building-experience/
If you would like additional information to have them added or on their current projects please let me know.
Regards,
Esther
