British pop star Sting helped generate a flood of funds for tsunami victims, with more than $4 million raised at his sold-out West Australian charity concert.

The veteran singer and international activist enthralled a crowd of 6,000 at the Leeuwin Estate winery in Margaret River with a two-hour gig dedicated to the Asian relief effort.

His mix of old hits such as Message in a Bottle and Every Breath You Take and songs from his current Sacred Love tour were lapped up by the ardent fans and corporate supporters who had paid a minimum of $150 a ticket to attend the benefit concert.

"I think you would be very hard-pressed not to have had a good night last night - Sting gave a fantastic performance," Leeuwin Estate's co-owner Trish Horgan said.

A tired but happy Ms Horgan confirmed the concert alone had raised at least $2 million, with money from bar sales and donations from local accommodation houses and businesses still to be counted.

The West Australian government has also pledged to match the funds raised dollar for dollar, making a total of at least $4 million.

"The money is still coming in," Ms Horgan said.

"As late as yesterday I had a donation of $50,000 given to me.

"People have been very generous and we're very pleased to be able to raise such a huge amount of money for this cause."

Ms Horgan said Sting and his band had been very happy with the outdoor venue, set in a large wooded grove on the Leeuwin property.

The pop star and his family were looking forward to a day on the local beaches and golf courses, she said.

Sting will hold a further two scheduled shows - also sell-outs - as part of Leeuwin's annual concert series on Saturday and Sunday nights.
