Andrew Humpherson (born 15 August 1960) is a former Australian politician, elected as a member of the New South Wales Legislative Assembly for Davidson from 1992–2007.
[6] The independents who held the balance of power subsequently forced Greiner's resignation as Premier, but ICAC was found to have exceeded its jurisdiction by the Supreme Court of New South Wales.
[9] Humpherson left ANSTO in late 2010 to establish his own government relations consultancy, Waratah Advisory, in anticipation of an expected Liberal win at the March 2011 NSW election and accepted a position as Chief of Staff to the newly appointed Resources and Energy Minister, Chris Hartcher.
In May 2012, Humpherson was accused by members of the state parliamentary opposition for continuing to be listed as the main contact for Waratah Advisory, with calls for his resignation.
Humpherson gained further attention when he took up a consulting role with the NSW Minerals Council two months after Hartcher's resignation, an action against a 2010 recommendation of the Independent Commission Against Corruption (ICAC) that former staff of ministers and parliamentary secretaries be banned for a year from lobbying activity "relating to any matter that they had official dealings within their last 12 months in office".
