In December, Sia will finally return to Australia to play her two biggest shows ever and you could be there no matter where in Australia you live.
Nova is giving you the chance to cop two tickets to the show in Melbourne or Sydney plus flights from wherever you are in Oz.
The Nostalgia For The Present tour is set to be one of the biggest of the year with Sia bringing Charli XCX, Mø and Amy Shark with her.
Sia is a huge supporter of marriage equality and she'll hopefully returning to Australia in December to a country that has legalised same-sex marriage. In order to win these tix, you've got to tell Nova in 25 words or less why you support marriage equality.
This would also be a good time to remind you that, if you haven't already, you'll be getting the same-sex marriage survey in the mail soon. Tick yes and send it off as soon as you can.
