Troye Sivan has won four gongs at the 37th ARIAs, including best solo artist and song of the year for his hit tune Rush.
Sivan, who has also been nominated for two Grammys (up against Kylie Minogue) was up on stage so many times on Wednesday night that he admitted he had run out of things to say.
"This has been the most insane week of my life ever ... it's really tripping me out," Sivan told the crowd at Sydney's Hordern Pavilion.
"To feel this much energy and love, I'm confused but I'm so happy."
With producer Styalz Fuego he also won two ARIAs for engineering and production.
Genesis Owusu also dominated the awards night with three ARIAs including album of the year for Struggler.
In a speech via video link from London, he called for a ceasefire and said the album was about humanity and community.
Owusu also took out best best hip hop/rap release and best independent release.
"Hip hop made me who I am and allowed me to speak on the things that I wanted to speak on, so I cherish it with my heart always," the Ghanaian-Australian singer said.
Earlier, Kylie Minogue won best pop release for her global hit Padam Padam, adding one more ARIA to the 17 she already has.
