If you are under the NBN FTTP (Fibre to the premises) technology, then connecting your Laptop directly to the NTD box will work given that you'll create a dialer to configure the PPPoE settings.
If you are under the NBN HFC (Hybrid Fibre to Coax) technology, then it will not work as you need a VLAN ID 2 configuration along with the PPPoE settings.
You may send me a PM with your TPG username or customer ID number if you need further assistance or contact our Tech team for real time support.
