The Coalition appears to be vastly better off than Labor, with the Liberals and Nationals making about $26 million more than their political opponents last year.

Donors appear to have cottoned on early that Labor had little chance of winning the 2013 election 

The 2012-13 annual data dump revealing corporate and personal donations to political parties shows the Liberal Party's total revenue was $73.1 million last financial year, compared with $54.7 million for Labor. The Nationals further bolstered the Coalition's haul with $8.3 million. The Greens recorded $8.1 million in revenue.

Labor relied to a large extent on unions for its funding. Union contributions totalled $5,418,419, with about $600,000 of that designated as "donations". The Construction, Forestry, Mining and Energy Union - which faces allegations of having links to organised crime - gave Labor $618,398.

The Liberal National Party received a combined $13.8 million in donations last year. More than $1 million of this came from mining and energy companies that enthusiastically supported Tony Abbott's campaign to remove the carbon tax. Woodside Energy, Hancock Coal, Chevron Australia, United Petroleum, Vector Resources, Northern Star Resources and Sundance Resources appear among a list of more than 20 companies associated with the energy and resources sectors.

The Australian Hotels Association, which succeeded in neutering Labor's promised anti-poker machine reforms, was again a major donor for both parties, giving Labor $150,000 and the LNP $372,500. Tobacco company Philip Morris gave $107,000 to the LNP.

Given the cut-off for the disclosures was June 30, these figures do not include money taken by parties during the 2013 election campaign.

The most generous personal donor to a political party last year was Roslyn Packer, the widow of billionaire Kerry Packer, who was once Australia's richest man. Mrs Packer gave the Liberals $580,000 in 2012-13, beating most corporate donations to the party and dwarfing all other personal donors.

Mrs Packer donated more than triple the amount given by the next largest donors, Huang Changran and Luo Chuangxiong, who each gave $150,000 to the Labor Party.

Mr Huang appears to be the chairman of Chinese investment company Yuhu Group, while a search of Fairfax Media's press archives back to the late 1980s reveals no record of Mr Luo.

Most individual donors who gave more than the disclosure threshold of $12,100 gave $20,000 or less.

Other notable personal donors to the Liberals included media mogul Harold Mitchell ($17,094) and Qantas chairman Leigh Clifford ($15,000).

Oddly, the self-proclaimed billionaire Clive Palmer donated $42,000 last June to his political enemy, the Queensland LNP. The donation came more than six months after Mr Palmer quit the LNP after a bitter falling out with Queensland Premier Campbell Newman. And it was only three months before the election in which Mr Palmer, running as leader of his own political party, the Palmer United Party, stole a House of Representative seat from the very party he sponsored.

Asked why he gave $42,000 to his political enemy, Mr Palmer said: "It wasn't a conscious donation from me." Mr Palmer said his wife and 19-year-old daughter had signed up for an LNP fund-raising dinner last January, and he did not have the heart to tell them they couldn't go. "I don't think you can tell women the way to think. They are entitled to their own views."

Donors appear to have cottoned on early that Labor had little chance of winning the 2013 election. The Liberal Party made nearly $20 million more in 2012-13 than in 2011-12 (when the party made $55 million).

Labor made only $5 million more last year than the previous year, in which it made $49.5 million. The party's most generous donors included chicken and turkey purveyor Inghams Enterprises ($250,000) and Chinese investment company Yuhu Group ($200,000).

Correction: An earlier version of this story incorrectly reported that more than $1 million of donations to the Liberal National Party came from mining and energy companies that supported Tony Abbott's campaign to remove the mining tax. They, in fact, supported the removal of the carbon tax.
