The year 2007 marked Fanning's sixth year on the ASP World Tour since 2002 and his ninth year on the ASP WQS since 1998. He began his 2007 World Title campaign (WCT) with a victory at the Quiksilver Pro, the first event on the 2007 ASP World Tour, putting himself on top of the ratings. He won the Santa Catarina Pro in Brazil on 6 November 2007 placing above Taj Burrow and Kelly Slate thereby clinching the 2007 ASP world title. In 2008 he suffered a mid-season groin injury. He slipped to eighth position on the end of year ratings. In 2009, Fanning reclaimed the ASP World Champion crown at the Pipeline reef break on Oahu's North Shore. Although Fanning was eliminated by fellow Australian Dean Morrison in Round 4, his points lead from winning three of the last four events was enough to secure victory. In 2013 he had a victory in Round five, and made the quarter-finals at the Billabong Pipeline Masters.
