Park Gold Cup, and lead the Blue Coral G-Force Porsche 911 GT1 driving line-up of Magnus Wallinder and Geoff Lister by 20 points, securing the championship before the season was even over. Having taken part in selected rounds of the FIA GT Championship in the previous season, Lister Racing made a full force assault on the international series in 2000, retaining the line-up of Campbell-Walter and Bailey. The duo were once again successful, taking the GT1 title with 59 points after five wins in ten races. Campbell-Walter also won the two rounds of the British Championship he took part in, alongside David Warnock, and won six events with a partial season in the TVR Tuscan Challenge. At the end of the season, Campbell-Walter was awarded the John Cobb Memorial Trophy for most outstanding performance by a British driver in international competition. For the following three seasons, Campbell-Walter remained at Lister Racing, taking another seven wins, and finishing fifth (2001), third (2002) and sixth (2003) in the drivers championship. Over those years he was partnered by Tom Coronel, Nicolaus Springer and Nathan Kinch. In 2002 it was awarded by Autosport Magazine Best international GT driver.

In 2005, he made a lone appearance in FIA GT to drive in the Spa 24 Hours for Russian Age Racing, taking the wheel of a Ferrari 550 Maranello. In 2006 Campbell-Walter also drove for the Red Bull BMW team in the Silverstone 24 hours race and won the race, his first 24-hour victory. In 2007 Campbell-Walter once again won the Silverstone 24-hour race in the Red Bull BMW team and also won the Dubai 24 hours race with the same team and car. For 2010 & 2011 Jamie joined the Sumo Power GT Team driving the infamous Nissan GTR in the FIA GT1 World Championship. The first was a huge success for such a new car and Campbell-Walter was teamed up with Warren Hughes. For 2011, Campbell-Walter has stayed with the team and has been joined by David Brabham youngest son of 3 time Formula One World Champion Sir Jack Brabham. For 2012, Campbell-Walter drove
