has been allocated to meet this requirement. In relation to the proposal to site a second airport in Williamsdale to the south of Canberra, Canberra International Airport indicated that they would not oppose this facility if the new site was also required to cater to a similar security regime as Canberra Airport.

Advertising While billboards have been barred in Canberra since the 1930s, an amendment of the National Capital Plan in 2000 allowed them to be displayed at Canberra Airport. Subsequently, the airport has hosted advertisements promoting defence hardware. A community group said the airport should not be promoting weapons manufacturers. The airport defended the ads and said the airport would continue to accept defence industry advertising. In 2015 the airport was lit up in rainbow colours, and in 2017 electronic and 3D message boards were used to support marriage equality. In August 2017 Canberra Airport awarded Qatar Media Services (QMS) the concession for all internal and external advertising. The first advertising project will be a double-sided "landmark digital billboard", being the only installation of this type in the ACT. Environment Approach and departure corridors lie over largely rural and industrial areas, although the instrument approach path (from the south) passes near the New South Wales suburb of Jerrabomberra, the city of Queanbeyan, and the Royal Australian Navy base, HMAS Harman, which has some barracks and housing. Proposals have been made to the NSW Planning Minister by various developers to approve housing estates that are under the southern flight paths in New South Wales. Canberra International Airport Pty Ltd has been vigorous in advertising its opposition to these plans on the basis of a general increase in noise levels over a wide corridor which is currently free of aircraft noise, and concern that this will lead to the imposition of a curfew on the hours-of-operation of the airport. Ground transport Access to the city from the airport is via Morshead Drive and Parkes Way and Pialligo Avenue to Queanbeyan. A major junction which connects the Majura Parkway and Monaro Highway with Canberra's east-west arterial road network is located adjacent to the airport. Travel time to Canberra from the airport
