Hi @Broncos87 ,
Welcome to the community!
Thanks for raising this to us. The shipment of NBN box will be done separately, you may track the status of the installation here, https://www.tpg.com.au/support/trackmyorder.
You will receive notification via email about the status of the shipment of the NBN box anda the actual installation date.
Let us know should you require further assistance.
I just recently signed up and received your TP Link however I never got a NBN connection device. Was I meant to get one?
