Despite the small margin, Baumann received a 7.3% swing in his favour, and notably this was the first and only time since formation of the electorate in 1988 that the seat had been won by a Liberal Candidate.

[2][3] After the Liberal party entered government at the 2011 election, Baumann was appointed by Premier Barry O’Farrell as Parliamentary Secretary for Regional Planning under Minister Brad Hazzard.

Following admissions by Baumann, at a hearing of the New South Wales Independent Commission Against Corruption (ICAC) on 12 September 2014, that he had written sham invoices to cover up electoral donations received from developers during his election campaign in 2007, he resigned from the Parliamentary Liberal Party and moved to the crossbench of the Legislative Assembly for the remainder of the 2011-2015 parliamentary term.

[4] With the announcement that the ICAC wouldn't bring down its report on Operation Spicer until after the 2015 state election, Baumann was forced to stand down as a candidate, with Kate Washington gaining the seat for Labor with a large 19.5% swing.

He was awarded a Centenary Medal in 2001 for "outstanding service to the development of the region through membership of the local Council".
