After winning the famous Bathurst 1000 race in 2000 with Jason Bargwanna, he found limited success and so moved to the new-look HSV Dealer Team for 2005, where he amassed a total of four race wins during the season.
Tander had never before won a race, let alone a round of the V8 championship, in his home state of Western Australia.
The three wins moved Tander to second in the V8 Supercar championship behind his Toll HSV teammate Rick Kelly who, for the most part of the weekend, was his only rival.

HOLDEN V8 driver GarthTander went out early in the top-10 shootout for the Sandown 500, posted a slick time of one minute 10.8817 seconds, and defied the championship series superstars to gamble on tyre and car combinations in changeable weather to run him down.
It was at Queensland Raceway in 2000 when Tander last occupied pole position, coincidentally in the same endurance classic which, at the time, had been shifted north to a circuit close to Ipswich.
Tander was on the podium in Darwin and at Queensland Raceway, and was close in the previous round at Oran Park.
