Australia's Eurovision decider draws 334,000 metro viewers

Australia has decided and the decision is final.

Sony Music-signed artist Montaigne won the judges ears and the hearts of Australia in a nail-biting finish for the Eurovision decider.

Broadcast live on SBS, 334,000 metro overnight viewers watched on to witness Montaigne leap ahead of runner up Casey Donovan with just seven points between them.

After winning over the public with 53 points, and a jury of industry experts with 54 points, Montaigne will go on to represent Australia at the Eurovision Song Contest in Rotterdam, the Netherlands in May.

“This is wild!" said the 24-year-old Sydney-based Montaigne, who will become the sixth Aussie acts to perform in the annual song contest.

She now follows in the footsteps of Kate Miller-Heidke, Jessica Mauboy, Isaiah Firebrace, Dami Im and Guy Sebastian.

"I started out just grateful to be a part of Eurovision but this is fricken insane!" she said.

"Thank you to everyone who gave me their vote, I’m so excited to go to Rotterdam and give it a red hot go!”

Her winning song 'Don't Break Me' was co-written with David Musumeci and Anthony Egizii of DNA Song.

Ten acts performed on Saturday night in a showcase hosted by Joel Creasey and Myf Warhurst from the Gold Coast.
