In Australia the predominant term used for SOEs is government business enterprise (GBE). Various Australian states also have GBEs, especially with respect to the provision of water and sewerage, and many state-based GBEs were privatized in some states during the last decade of the twentieth century. Former Commonwealth SOEs include Telstra, established in the 1970s as Telecom Australia. Telstra, now Australia's leading telecommunications company, was privatized in 1997 by the government of John Howard. As of June 2010 Telstra owned a majority of the copper wire infrastructure in Australia (the rest is owned by Optus) and is pending sale to its former parent, the Australian government, for a non-binding amount of 11 billion Australian dollars, as ducts in the copper wire tunnels are needed
