The ACT government could open almost all of its information, even cabinet papers, to potential public scrutiny under a plan developed by one of its ministers.
Shane Rattenbury, the sole Greens MLA in the Labor-led government, has drawn up legislation that would make the territory the most transparent jurisdiction in Australia.
His draft laws also carry fines of up to $14,000 for public servants who wrongly suppress documents.
Mr Rattenbury's freedom of information bill proposes abolishing the government's right to automatically prevent the release of certain documents, such as cabinet briefs, internal advice or information about businesses.
Instead, if a member of the public requests access to such a document, an official will need to consider the public benefits in releasing it before making a decision, and try to release at least some information.
The legislation would also force government agencies to publish online a range of documents regardless of whether anyone asked for them, such as reports from experts, minutes from committee meetings, ministers' official diaries, and summaries of cabinet decisions.
A similar attempt to encourage "proactive disclosure" in the federal bureaucracy, introduced in law in 2010, largely failed, as government agencies elected to publish very few documents.
However, Mr Rattenbury's bill is more prescriptive and would force agencies to publish a wider range of information.
The Greens politician's push for more open government contrasts with the views of some senior federal public servants, who spoke out recently against FOI.
Public Service Commissioner John Lloyd said last week FOI law was "very pernicious", "less than ideal" and discouraged public servants from putting their advice in writing. Treasury head John Fraser has expressed similar views previously.
Mr Rattenbury's proposal is not yet government policy; it remains under negotiation between Mr Rattenbury and the Labor Party.
In return for Greens' support after the 2012 election, Labor agreed to back a rewrite of FOI law based on Queensland's Right to Information Act, widely seen as Australia's most open.
Information law specialist Peter Timmins said Mr Rattenbury's ideas, if made law, "would be widely regarded, even internationally, as very best practice".
He said few jurisdictions in the world had abolished governments' "exemption" power, the ability to suppress all documents of a certain type.
"It sounds like this is a very significant move away from what's been the basic design of FOI legislation in Australia," Mr Timmins said.
Mr Rattenbury said he was confident Labor would agree to the legislation but it might request some changes.
He said he thought Mr Lloyd's view was wrong, as it failed to take into account the benefits of making government documents and data public.
"It helps citizens participate in government, and that can lead to better government," he said.
The minister said that when his department made more information about bike accidents and roadworks public, it had encouraged people to start helping the government.
"Now people are starting to write to me and offer some really interesting analysis," he said.
"In the long run, it actually saves time and money for governments to get their information out there and see it used in really effective ways."
