Vodafone have added BYO option to their NBN plans. Critical Information Summary
Same as the post here but no more modem contract
The conditions of the BYO plans appear to be the same.
I couldn’t find any options to sign up online so I signed up by chat.
One thing missing will be the 4G backup option. Not sure if you can utilise that option in BYO if you have a Vodafone Wi-Fi hub from somewhere else.
