The Australian gas industry was deregulated in 1997. This required retailing functions to be tightly 'ring-fenced' from the ownership and operation of gas distribution networks. The networks are subject to open access which allows multiple retailers to compete for customers in markets previously considered monopolies.
Overview of regulatory regime
In November 1997, the State and Federal Governments signed the Natural Gas Pipelines Third Party Access Agreement which set out the terms and conditions under which deregulation was to occur.
Full retail contestability occurred in Victoria in October 2002, in South Australia in July 2004 and in Queensland from 1 July 2007.
From 1 July 2008, the Australian Energy Regulator (AER) took over responsibility for economic regulation of the gas distribution and transmission sectors.
