The Western Australian Liberal Party received almost three times as much as the Labor Party in political donations last financial year, official data shows.

The WA Electoral Commission's 2013-14 annual disclosure of gifts and other income by political parties also showed the Greens attracted a record amount on the back of Senator Scott Ludlam's successful re-election campaign.

The Liberals collected $9.9 million, with donations from across the business community.

In the previous financial year the party received $11.3 million, which included the March 2013 state election funding boost.

The Western Australian ALP attracted $3.5 million in 2013-14, mainly in donations from unions, compared to $5.8 million in 2012-13.

However, the national branch of the ALP paid for the April 5 re-run Senate campaign, while the WA Liberals paid for it themselves.

WA Liberal Party state director Ben Morton said nothing had changed.

"The figures show that the ALP, despite election blow after election blow, still allow their campaigns to be run from the eastern states rather than from Western Australia," he said.

"And that they are still a subsidiary of the union movement."

But Labor's Margaret Quirk hit back, saying it was not surprising big business gave generously to the Liberals.

"This is about buying access to the Government and that's not how Labor works," Ms Quirk said.

The ALP party received hundreds of thousands of dollars from affiliated unions but also donations from Woodside, Chevron, Mineral Resources and property developer Nigel Satterly.

The Liberal Party was given $385,000 from its associated entity and conservative fundraiser The 500 Club, as well as donations and other gifts from resources and construction companies such as Chevron, FMG and BGC.

The Greens raked in almost $3.2 million in 2013-14, a massive increase on the $1.3 million it collected in the previous financial year.

The party ran an extensive campaign to re-elect Senator Ludlam in the disputed April Senate election, with tens of thousands of door-knocks, cold calls and a series of public lectures on Greens policies.

Senator Ludlam also generated more than $100,000 in donations for the party after a YouTube video of him speaking in the Senate on March 4, inviting Prime Minister Tony Abbott to WA, went viral on social media.

The party's largest individual donor was once again Cottesloe's Ruth Greble, who gave $307,600.
