Welcome to the Community!
The standard NBN installation time frame is 2-30 days.
I checked your address and found that the type of service you'll get is NBN HFC which utilizes a coaxial connection. You therefore won't be using a phone socket. Instead, an NTD (Network Termination Device) will be connected to a coaxial wall socket. Your modem will then be connected to this NTD for it to work.
In addition, your location is tagged as Service Class 23 which means that on the record of NBNCo, there's already an existing coaxial wall plate in the house. This means, that the NBN technician will simply have to bring and install the NTD.
Let me know if you need clarification.
