Stewards decided against imposing any sanctions following an investigation into a clash between Shane van Gisbergen, Garth Tander and Jason Bright in Race 11 at Darwin.
Officials reviewed the incident that saw van Gisbergen, Tander and Bright make contact at Turn 6 while fighting for position on lap 39 of the 42-lap affair at Hidden Valley.
The nose of van Gisbergen's Red Bull Holden tagged the side of Tander's Garry Rogers Motorsport Commodore, before then being squeezed by Bright's Ford.
The contact broke the steering on van Gisbergen's car which then resulted in further contact with Tander, ultimately ending in retirement for the former.
Following a thorough review, stewards determined neither driver was wholly at fault for the incident.
While this incident escaped penalty, wildcard runner Macauley Jones has been issued with four-place grid drop to be taken in Sunday's Race 12 for causing contact with Nissan Motorsport's Michael Caruso on the opening lap.
The incident resulted in Caruso spinning his Nissan Altima at Turn 13, losing positions in the process.
Officials also imposed a 27 second penalty to be added to Alex Rullo's race time for spinning his wheels while the car was been serviced in the pits.
The penalty has seen Rullo drop from 21st to 24th position in the results.
Stewards deemed investigated clashes between wildcard Jack Le Brocq and Nissan's Simona de Silvestro, and an opening lap incident involving Prodrive's Mark Winterbottom and Erebus Motorsport's Dale Wood.
Neither incident warranted a penalty following a post race review.
