In your address available nbn technolgy is FTTC. AS per NBN previously there was active nbn FTTC service so nbn NCD should be in premise. In case if you unable to find out contact property agent to check with previous occupant because most of times previous occupant taking that nbn ncd with them when moved. Right now i am able to see that your service is awainting for device installation. If you find out your nbn ncd then it make your activation quicker than involving nbn particularly in time.
I have also reported about corroded socket to Engineer, due to this pandemic its take longer than usual to comeout but Engineer will check with NBN and base on that They can advise to you.
