The 2016 Supercars champion also defeated Tander and Supercars rival Chaz Mostert in the opening Fanatec GT World Challenge Australia Powered by AWS on Saturday, before being pipped by Tander on Sunday morning.
The current Repco Supercars Championship leader claimed pole for Sunday’s six-hour race, but was forced to overcome a five-second time penalty in the final stint.
Five seconds were added to the #97 BMW’s race time following a restart breach, but van Gisbergen crossed the line nearly 13 seconds clear of the #1 Tim Leahey/Beric Lynton BMW M3.

Another of van Gisbergen’s fellow Supercars drivers, Tim Slade, finished fourth overall alongside Bradley Carr, with their #8 BMW M3 missing out on victory after a number of issues in the race.
Critically, Slade had to pit from the lead with just over an hour to go after a tyre issue.
Erebus Motorsport’s Brodie Kostecki, who claimed his maiden Supercars podium at Sandown last month, combined with Morris and George Miedecke to finish fifth outright, winning the A2 class.
Van Gisbergen won the 2020 Bathurst 1000 alongside Tander
Morris previously won the Bathurst 12 Hour in 2007 and 2010, before winning the Great Race alongside Mostert in 2014.
Mostert previously won the inaugural Bathurst 6 Hour alongside Nathan Morcom in 2016.
Sunday’s result marked another key success for van Gisbergen, who is continuing his recovery from a broken collarbone sustained early last month.
