The album, titled #SayYesToLove Vol. 1, was coordinated by advocacy group Australian Marriage Equality (AME).

It will feature a mixture of pre-existing tracks, new cover tracks, and brand-new songs. Other artists to feature include The Basics, Katie Noonan, The Cat Empire and Wes Carr.

"We've got a really great collection of well-known artists and also incredible up-and-coming artists as well," executive producer Michael McGlynn told BuzzFeed News.

All proceeds from the album, which will be available via iTunes this Friday, will go towards AME's campaign.
