A long-awaited report by the NSW Independent Commission Against Corruption proposes a radical overhaul of lobbying and transparency regulation in a state well known for persistent corruption and influence-peddling all the way up to the premier's office.

It also serves to demonstrate just how primitive and corruption-centric Commonwealth requirements around lobbying of decision makers are.

NSW has a legislated framework for lobbying, established by the O'Farrell government after ICAC made a major series of recommendations in 2010 in response to years of corruption under the NSW Labor Party. Barry O'Farrell's successor, Mike Baird, established a requirement for ministers to publish quarterly meeting diaries online. Both put NSW far ahead of the Commonwealth in relation to transparency and lobbying regulation.
