Greens leader Bob Brown says he expects criticism after his party received the biggest political donation in Australian history.

The Greens are continuing to campaign for political donations from individuals to be capped at $1,000, despite Wotif founder Graeme Wood's $1.6 million donation before the last federal election.

"While the big parties block [us], the Greens are going to continue to get a disproportionate increase in funding," he said.

"Maybe it will be that factor which will get one or other of the big parties to bring in restrictions on political donations."

Senator Brown says Mr Wood's donation was used for television advertising in the final weeks before the election and contributed to the party's record vote and first House of Representatives gain.

"The opponents will hate it," he said.

Senator Brown says he will be "forever grateful" for the donation but Mr Wood will not get any special treatment.

The previous highest donation was made by the conservative British MP Lord Michael Ashcroft to the Liberals in the 2004 campaign.

The total amount of donations to the Greens during the election campaign will be revealed next week, while donations to the major political parties will not be revealed for another year.
