Some of Australia's biggest music names are set to join forces this month for a nationally-broadcast benefit concert in support of marriage equality. 

The LiveAid-style gig, coined YesFest, will go down at Sydney's Spotless Stadium on 29 October and feature a huge bill that includes Flight Facilities, Killing Heidi, KLP, Megan Washington, Nick Cester (Jet), The Preatures, Tkay Maidza, special guest, Jimmy Barnes, and many more still to be announced. 

All proceeds from the benefit show will go towards peak body, Equality Campaign. 

"When I was asked to do this show I jumped at the chance to say Yes because I believe in marriage equality," Barnes said.

"Love is love and if you are lucky enough to find the one you love, why should anyone be able to tell you - you can’t get married. It’s a basic human right."

Tickets for YesFest go on sale from midday today; for more details, check out the festival website.
