An impressive part-time drive in the 1999 V8 Supercar championship saw the Holden Racing Team offer McConville an endurance co-drive, pairing up with the then championship leader Craig Lowndes. Together they finished in second place at the Bathurst 1000 race. This performance earned him a full-time contract with the newly expanded Rod Nash Racing for 2000. In 2001 he moved to the Sydney-based Lansvale racing team where he continued to impress in under-funded, less-developed machinery. He remained with the team until he was offered a contract with the Garry Rogers Motorsport outfit in 2004 after he was the outright winner of the Bathurst 24 hour race in 2002 in a Holden Monaro driving for the same team. The move to the Garry Rogers team proved fruitful for McConville when he took his first championship race win at Winton Raceway in 2004. In 2005 he took on team leader status at GRM with the departure of Garth Tander to the HSV dealer team. The following year, McConville was lured to Kees and Paul Weel's Supercheap Auto Racing outfit to pair with Greg Murphy after the retirement of Paul Weel in 2005.
