However, the Sydney event is a 200km which will be the only dusk/night race of the season followed by a 140km encounter.
As previously reported by Speedcafe.com, there will be shorter races at Albert Park to accommodate the addition of Formula 2 and Formula 3 to the Formula 1 Australian Grand Prix programme, with a 100km affair followed by an 80km and two 70km contests.
The rest of the sprints are trios of 100km races, with Supercars Championship action compressed into two days at Symmons Plains and The Bend, as well as Sydney.
All up, there are 28 races across the 12 events summing to almost 5400km.
All 200km and 250km races have two compulsory two pit stops, with refuelling, while the sprints will have a mandatory two-tyre change.
The exception to the latter is Albert Park, where mixed tyre compounds apply and all four tyres must be changed in a stop.
Where a shootout is not used, qualifying is a mixture of knockout (Format 2) or single-part sessions (Format 1).
As far as points are concerned, it is again a case of a total of 300 for race wins, spread equally across as many races as there are in the weekend.
Formats for Super2 have also been confirmed and are essentially unchanged.
