If you’re moving into or living in a property that has an existing connection to the SIP’s network, you may not deal directly with your local SIP.
You probably deal directly, and have a contract, with a retailer like Telstra. For example, Telstra may be your retailer and sends you bills.
Your SIP may be NBN Co, but they don’t send you bills.
In this case, NBN Co sells internet connections to retailers like Telstra (and not consumers), and retailers sell them to you.
So, while you don’t usually deal directly with your SIP, they may need to contact you if they need to send a technician and want to arrange a time with you.
If you’re building a property, knocking one down and rebuilding it, or substantially altering one, you or your builder need to speak and work with your SIP.
In these cases, you’ll need to submit a development application to your SIP to make sure you install the right infrastructure to connect to the SIP’s network.
If you’re moving into a newly built property, a SIP may charge you a new connection fee through your retailer.
