Hey there, @Kevin295919, and welcome to the forums.
Absolutely that would work.
It’s a very simplified explanation, but a router is really just a computer with IPv4 route tables and a NAT Gateway. Most routers already use Linux so the software side of things shouldn’t be too hard to find. You’ll just need to set the Optus IP as the OUT interface, set up a NAT Gateway, and have the Pi’s WiFi and Ethernet configured as the IN interface. Then you just need to configure your routing tables to send all internet traffic OUT and all private traffic within the LAN, but it’s totally doable.
I would recommend getting a USB to WiFi antenna for the Pi as it’s native antenna is not quite sufficient for using it as a WiFi router (apart from very small distances).
