RAAF Hornets have also provided air defence for several high-profile events in Australia since the 11 September attacks. In 2002, Hornets patrolled over the Commonwealth Heads of Government Meeting (CHOGM) at Coolum Beach, Queensland; this was the first time RAAF aircraft had flown air defence sorties over Australia since World War II. On 22 and 23 October that year a detachment of Hornets patrolled over Canberra during US President George W. Bush's visit to the city. A detachment of aircraft from No. 77 Squadron was deployed to RAAF Base East Sale in March 2006 to protect the Commonwealth Games, which were being held in Melbourne. In September 2007, Hornets patrolled over Sydney during the APEC leaders meeting there. Eight Hornets were also deployed from Williamtown to RAAF Base Pearce in October 2011 to protect the CHOGM meeting in nearby Perth. On 16 and 17 November that year, Hornets operated over Canberra and Darwin while President Barack Obama was present.
