Awkward installations expensive, note fibre optic is more fragile than copper.

FTTB (Fibre to the Building) in 2014, FTTC (Fibre to the Curb) in 2018, but in particular FTTN (Fibre to the Node) in 2015 accelerates rollout. They used VDSL2 (very high speed DSL over Telephone Cable) its power boosted up to 30MHz, its download speed varying

Points of Interconnect (POI)

How do POIs work?

POIs are nodes that connect your home to the internet, a multi-step process

  1. In your home, you'll have your devices connected to your modem-router, wired or over WiFi
  2. Your modem-router is connected to an NBN access point where the data is stripped of its local protocols, converted to standard Ethernet frames, and forwarded to the nearest NBN Point of Interconnect
  3. This is then connected through to your RSP Network (Retail Service Provider), patched through to an international network, where you can access websites and browse the web.

Where is my POI?

Usually housed in select telephone exchange buildings, there's 121 across Australia's states, servicing every household on the network.

Below is a list split up by state.

New South Wales POIs

Queensland POIs

Victoria POIs

Western Australia POIs

South Australia POIs

ACT POIs

Tasmania POIs

Northern Territory POIs

An Interim POI is to be utilised when a permanent POI has not been developed, typically in new areas. When a permanent POI is established, household internet traffic will go through newly created POI.
