Welcome to the Community!
We were able to locate your account using your community details and learned that your service is affected by an unplanned network outage. You may search your address here (https://www.nbnco.com.au/support/network-status) for the information.
We've checked this case with NBN Co and learned that their attending field tech has traced the issue to an exchange that is located in a building that is currently closed. They will contact the building management on Monday to arrange access for field techs.
Our sincerest apolgies for the inconvenience.
