Kimbra has won the ARIA for Best Female for a second year running.
The New Zealand born, Melbourne-based singer - who was wearing a red sequined body suit with a large red tulle skirt - beat bookies favourite Missy Higgins to claim the Australian music award.
The category featuring Jessica Mauboy, Washington and Lanie Lane was one of the strongest from the nominations draw.
The award was presented by British comedian Russell Brand, who brought his mum on stage to present the award.
He pointed to her tummy and said: "I used to live in there. I came out here to be with everyone else."
Just before receiving her ARIA, Kimbra performed a kooky version of hit 'Settle Down'.
"This means a lot to me and these things are brutal ... What a whirlwind year it's been and what an amazing way to top it off to be acknowledged for this record I started making in Melbourne at 17."
Kimbra had earlier strutted down the ARIA Awards carpet in a flamingo-looking pink feather dress in sweltering heat as fans screamed.
The Hamilton-born singer won the ARIA award for best female artist in 2011, and earlier this month picked up five New Zealand music awards.
She again won on Thursday for best female artist for her breakthrough album Vows, which made an impact in the United States as well as Australia and New Zealand.
Australian bookies had favoured Higgins, who made a spectacular return with her third album The Ol' Razzle Dazzle, ahead of the other strong performers.
Kimbra had also been up for best pop release for Vows, which ended up going to Gotye, who was her singing partner on the smash hit 'Somebody I Used To Know'.
Vows has been certified gold in New Zealand, where it debuted at No 3, and Australia, where it debuted at No 5, while it also reached No 14 on the US Billboard chart.
Kimbra's five New Zealand Tui awards included best female solo album and album of the year.
