In 2003, largely due to concerns that Adelaide's urban sprawl was encroaching onto surrounding farmlands, the then State Planning Minister Jay Weatherill made a commitment to contain the expansion of Mount Barker. In 2008 a consortium of five developers sought the rezoning of of prime agricultural land in order to build an additional 7,700 new homes which would increase the population of Mount Barker from 10,258 to around 35,000. The land included rezoned to light industry in order to provide jobs for the new population. The plan was rejected by the Mount Barker Council as it had just completed a 15-year development plan for the area that would retain the town's "rural character" and it could not afford the required infrastructure, a decision supported by a survey indicating that the rezoning was opposed by 98% of residents. In April 2009, the developers approached Paul Holloway, the State Planning Minister, to override the council decision, arguing that the land had "no outstanding attributes except for its suitability for urban development." In May 2009 the Minister announced that his office would go ahead and bypass the council. The following month Mark Parnell, the SA Greens representative in the South Australian Legislative Council made a request under the Freedom of Information Act 1991 for copies of documents passed between the developers and State Government. The State Government in December 2010 approved the rezoning and development and construction began without the usual council infrastructure however, the state Government agreed to a $550 million infrastructure support package. The rezoning also included amending the area's bushfire risk level from high risk to only a general risk. The council expressed concern that the reduction of the threat level would lead to a reduction of building standards compared to those standards required for homes in high risk areas and pointed out that the previous year, Victoria's Black Saturday bushfires Royal Commission had recommended that there should be less building in bushfire-prone areas. The FOI documents, released in February 2012, indicated conflict of interest and poor planning practices. One document revealed that the Minister had ignored Planning SA's request not to make any commitments to the developers before the state's own 30-year plan was completed. South Australia's Planning Minister John Rau (2010–present) said that the Government should not have approved the rezoning of land without the government and council being able to support that community with infrastructure. The Government has since announced it will reform the state's planning process, calling it "dishevelled, disjointed and inconsistent". A new interchange on the South Eastern Freeway at Bald Hills Road has been built to improve travel times and road safety for commuters travelling to the east side of Mount Barker and reduce traffic congestion in Mount Barker.
