Welcome to TPG Community!
We have some customers who were able to configure their ASUS DSLAC68U with TPG NBN.
Here are the link: ASUS DSL AC68U on TPG HFC, Can you connect an ASUS DSL-AC68U to NBN
You need to make sure that the modem is configured with VLAN ID '2' and PPPoE (With TPG username and password).
If it's still not working, you may need to contact ASUS support for further checking.

I followed the method over the weekend and finally have my DSL-AC68U connected to TPG FTTC. You'll end up with 3 devices connected (NBN modem, TPG router acting as a bridge and then ASUS) but will at least have a decent router connected.

This worked with HFC using VLAN ID 2. In theory, it should work with FTTC if all that is needed is to set the router to VLAN ID 2.
I can confirm that I got the DSL-AC68U working with FTTC - see "work-around" instructions here
It is indeed everything to do with the VLAN ID 2. Let me know how you go!
