Orbi RBR50 not allow Granstream HT801 to register

What is the Orbi connected to? (brand & model)

Is the Orbi is "router" or "access point" mode?

Was the previous Optus modem/router an "all in one" device?

Have you looked at the installation steps describing NAT?

Are you using same SSID name and password on the Orbi as you did on the prior router?
