The Network Boundary Point (NBP) is the end of the network that nbn is responsible for — anything beyond that point is the responsibility of the customer or property owner.
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 lead-in cable from the street connects first.
However, some homes might have an external telecommunications box, like a lead-in box. If this is present, then the lead-in box is considered your Network Boundary Point.
If needed, a technician can determine the NBP location during any investigation or fault diagnosis.
🏢 For units, apartments or office blocks (multi-dwelling premises)
The most common NBP is a centralised telecommunications cabinet or room known as a Main Distribution Frame (MDF).
The cabling and any equipment between the MDF and the first socket in your apartment/unit is generally the responsibility of the building owner, body corporate or strata.
