Promoters of an Australian music festival headlined by Flume say the inclusion of just one female act on its bill was an oversight that will soon be rectified.

Canberra festival Spilt Milk features Flume at the top of a line-up that also includes Hermitude, Violent Soho, Vince Staples, Sticky Fingers and Gang of Youths.

But the bill features just one woman - Sydney-based singer-songwriter Vera Blue.

The lack of more female artists led to criticism through the festival's Facebook page and on Twitter, reports


Only ONE female artist in Spilt Milk's 2016 lineup... Do better," wrote one critic.

In a statement, Spilt Milk promoters said they would rectify the situation with a second line-up announcement.

"Gender inequality exists throughout society and we all have an obligation to help foster change, an opportunity we missed with our initial announcement," they wrote.

"Assembling exciting lineups for events of this nature is incredibly complex, with many different, and often competing, contributing factors.

"With our growing understanding of this issue, and recognising that every small step matters, we are committed to delivering more opportunities for female artists to help move the industry in the right direction."

Spilt Milk is set to be held on December 3.
