Brisbane G20 summit: Airport bans political billboards ahead of forum After first claiming a climate change ad was too political, Brisbane airport authorities have also rejected an advertisement highlighting corruption problems. They're getting ready for the G20 at Brisbane Airport both on the runways and outside. Picture: Leonie Vandeven / AAP Source: AAP The C20 - a forum launched for dialogue between the political leaders of the G20 and representatives of civil society organisations - wanted to place advertisements in lightboxes at the airport to raise issues such as tackling poverty and improving infrastructure. But advertising agency oOh!Media, which is under contract to Brisbane Airport Corporation (BAC), told C20 organisers they could not because of the political content. The same policy was applied when banning ads by anti-corruption lobby group Transparency International (TI) and a group of environmental organisations - including GetUp, Greenpeace and WWF - wanting to put climate change on the G20 agenda. Groups including GetUp, Greenpeace and WWF have created these billboards but they're too political for G20.

Serial pest Peter Hore, who has a long history of disrupting major public events including the funeral of former INXS frontman Michael Hutchence, and major sporting events like the 1997 Melbourne Cup and a Socceroos" World Cup qualifying match, has been banned from G20. The 54-year-old admitted to The Courier Mail he wanted to "walk naked across the Gateway Bridge" during the summit. He has been officially banned from the G20 by police, becoming one of two people on the Prohibited List, meaning he's not allowed to be in Brisbane from November 8 to 17. Expectant parents are also facing exclusion issues, with one of Brisbane's busiest hospitals sitting in the city's restricted security zone. Pregnant women who go into labour during G20 have been advised to call an ambulance if they want to be sure of reaching the Mater Mothers" Hospital in time. Read more at the Courier Mail.
