Powderfinger is going out on a high, quite literally. The Australian rock group has raised more than $150,000 Australian ($148,000) for charity in a unique high-flying stunt just days before wrapping-up their towering career.

The veteran five-piece performed a 45-minute live set during an internal flight on the Jetstar low-cost airline.

Powderfinger fans bid on eBay for the in-flight packages, which included return airfares from Sydney to the Gold Coast, a VIP lounge party with the band and a signed copy of their final studio album, "Golden Rule". Some fans paid close to $10,000 Australian ($9,880) for the privilege.

The cash raised last Thursday (Oct. 28) will benefit charities the Yalari Foundation and World Vision.

Powderfinger's plane is coming in to land after a remarkable career, which saw the group sell upwards of 2.5 million albums and gather more than 16 ARIA Awards.

There may be more gongs to come when the ARIAs are presented this Sunday (Nov. 7) in Sydney. The Brisbane-based group will perform at the industry gala where they are nominated in four peer-voted categories, and shortlisted for a pair of fan-voted awards, introduced to the mix for the first time this year.

Powderfinger will close their career keeping intact a streak of five chart-topping studio albums, which began in 1998 with "Internationalist" and runs through to the double-platinum certified "Golden Rule," which opened at the national chart summit following its release last November.

The band's farewell "Sunsets" tour has shifted more than 300,000 tickets across 34 shows in 21 different cities, and will conclude Nov. 13 with the final of a three-night stand at the Riverstage in the band's hometown, Brisbane.

"The tour has been absolutely awesome, amazing. There's a lot of love out there," frontman Bernard Fanning tells Billboard.biz. "No-one has been too sentimental or sad about [the band splitting]. People are just happy to have been a part of it. It's just a great feeling to have to know that you've given people a lot of pleasure."

Although the band members remain friends -- and some will collaborate on music projects - there's no intention to revive Powderfinger. "We're approaching the end of the road. The yellow and black stop sign at the end that says, 'go no further'," guitarist Darren Middleton tells Billboard.biz. Splitting after 20 years "feels right," he adds.

Universal Music Australia will issue on Dec. 3 the commemorative "Sunsets Farewell Tour" on DVD and Blu-ray.
