Last updated: 17 May 2026<\/p>\n\n\n\n

If you need to phone someone about your NBN, the first question is: who do you actually need to call? In almost every case it’s your retail provider (Telstra, Optus, Aussie Broadband, Tangerine and so on) \u2014 not NBN Co. NBN Co only handles the physical network. The plan, billing, modem, faults and the human on the end of the line all come from your provider.<\/p>\n\n\n\n

Below are the current contact numbers for the major Australian NBN providers, plus NBN Co for the few situations where you do need them. The table below is generated live from our provider database, so the numbers stay current.<\/p>\n\n\n\n

NBN Co vs your retail provider \u2014 who does what?<\/strong><\/h2>\n\n\n\n

This trips a lot of people up. NBN Co owns and operates the physical fibre, copper and HFC infrastructure that runs to your house. They don’t sell internet plans to customers, they don’t bill you, and they don’t run the call centre that talks to you when your internet is slow.<\/p>\n\n\n\n

Your retail service provider<\/strong> (RSP) \u2014 Telstra, Optus, Aussie Broadband, Tangerine, Exetel and so on \u2014 is the company that sells you a plan, sends the bill, supplies the modem and is your first port of call for almost everything. When you call them about a fault, they run the diagnostic, and if the fault is on NBN Co’s infrastructure, your provider lodges the ticket with NBN Co on your behalf. You don’t need to deal with NBN Co directly.<\/p>\n\n\n\n

The rare exceptions where you’d call NBN Co directly are listed further down.<\/p>\n\n\n\n
