Good day @craig210788,
Welcome to TPG Community!
If you have an NBN ready Netgear D7000 modem/router, you will be able to use it on your TPG NBN service, however, the home phone will not work on it.
Me and @Jasonlouey74 were able to configure his own Netgear D7000 modem/router using the settings below.
First, you need to access your Netgears User interface by typing the numbers in the address bar as 192.168.0.1 or 192.168.1.1. (Assuming that you are already connected to your Netgear modem)
Then follow this settings:
Keep us updated if it worked or not.
I've seen some people did this but not sure if it's for D700 as well
but the idea is if it's for HFC you have to set your Netgear as a wireless/home gateway to enable the WAN/Internet Port instead of the ADSL/VDSL port.
For some netgear it should be on advance tab -> set up -> XDSL
then go to internet settings and enable VLAN tagging and set it to 2
use PPPoE for the connection type and enter your TPG UN and PW
