Ok guys slight change of plans to the track layout, here is the official statement from AASA to the WRX club.
** URGENT UPDATE **
To meet national safety requirements of the AASA at the Calder circuit, an additional man made chicane will be placed on the back straight between Turn 5 & Turn 6 to limit competitors speed prior to entry of T6. The chicane will be constructed from water filled barriers.
Should the track be declared a wet day then an alternative configuration will be used encompassing the use of pit lane (with speed restrictions) as part of the track, avoiding the main straight where drag racing is held.
We are working closely with they WRX club, AASA, Calder Park and WAP to find an alternate solution. I will keep eveyone updated if we have any other changes.
