Controllers in a TCU use radar and other surveillance technology to manage the flow of aircraft arriving and departing from major city airports. Airservices provides air traffic control services in an extended area around capital city airports, and maximize the safe use of this airspace. The TCU services are provided around the following major airports: Adelaide, SA (integrated into Melbourne Centre, as of mid-2017) Brisbane, QLD (integrated into Brisbane Centre) Cairns, QLD (integrated into Brisbane Centre, as of mid-2017) Canberra, ACT (integrated into Melbourne Centre) Hobart & Launceston, TAS (located in Melbourne Centre, commenced 16 June 2022) Mackay & Rockhampton, QLD (located in Brisbane Centre, commenced 16 June 2022) Melbourne, VIC (integrated into Melbourne Centre) Perth, WA (shared facility with Pearce air traffic controllers, located at Perth Airport) Sydney, NSW (located at Sydney Airport) Area control centres Airservices Australia manages 11 per cent of the world's airspace, including very large portions of the Indian and Southern Oceans, and parts of the Pacific Ocean and Tasman Sea. The airspace consists of two flight information regions (FIR), the Brisbane FIR and the Melbourne FIR. Each FIR is managed by its respective area control centre (ACC), which provide en-route services. Brisbane Centre The Brisbane FIR consists of New South Wales north of Sydney, all of Queensland, most of the Northern Territory and the northern half of Western Australia. It also contains the Australian Tasman Sea airspace. Due to the nature of the airspace, it controls most international flights in and out of Australia (except Indian Ocean flights), and domestic flights operating to airports within the FIR. As only two of eight capitals are located in the Brisbane FIR, it handles a lesser volume of traffic than Melbourne Centre. However, Sydney is just south of the border of the two FIRs (the Sydney Basin is part of the Melbourne FIR), and thus Brisbane Centre has control of flights arriving or departing in Sydney from the north.
