There is always their own streaming service for those outside US/NZ called superview. Its about 40 bucks, but gives you every quali and race session live or on replay. Plus this year also included their e-sports series and a behind the scenes Documentary for one of the race teams. For 30 races its not bad value, just a shame they remove the previous season when the new one starts . They sometimes also do a 'Bathurst only' deal. but not sure if they have this year.
There are also less legitimate ways, but we wont discuss those here.
