Hi @j15hillhouse ,
Welcome to the community!
I checked on Google and it seems that TP link archer vr600 is a VDSL modem/router if this is the case, you can use it with TPG/NBN FTTB service you simply need to set up VLAN ID 2 and connection type PPPoE together with your TPG Username and Password, that should work.
Let us know how it will go and should you require further assistance.
Regards,
