The Network Boundary Point (NBP) is the point where the nbn® network ends — and where your responsibility (or your building’s) begins.
Think of it like the “handover point” between the network and your home or building wiring.
Where your NBP is located depends on the type of building you’re in.
🏡 For standalone homes (single dwelling premises)
The most common NBP is the ‘first socket’ inside the house — where the connection from the street comes in.
Some homes also have an external telecommunications box, like a lead-in box. If that’s present, that becomes your Network Boundary Point instead.
If you’re ever unsure, a technician can confirm the exact location during a fault check or install.
🏢 For units, apartments or office blocks (multi-dwelling premises)
The NBP is usually a shared connection point like a Main Distribution Frame (MDF).
This is where the external network connects to your building.
Anything between the MDF and your individual unit (like internal building cabling) is generally the responsibility of the building owner, body corporate or strata — not the network.
