"Julia Gillard, Christine Anu, Emma Donovan, the 18-member Marliya girls' choir from Cairns and all of the wonderful participants in WOW Australia 2020 will ensure achieving gender equality and creating more opportunities for women and girls remain part of our ongoing conversation.

"The WOW event held during the 2018 Gold Coast Commonwealth Games was an enormous success with more than 5,000 people attending for a fun and energetic celebration of women and girls, and I'm proud this event is returning to Queensland."

Minister for Education and Member for McConnel Grace Grace also attended today's program launch at the Brisbane Powerhouse.

"The Palaszczuk Government is committed to increasing the representation of women in the workplace, in business, the arts, in sport and in the community and this festival will help people come together in the spirit of fun to imagine a better world of equality and provide solutions for change," Ms Grace said.

"I encourage everyone to be part of this fabulous event."

WOW Australia 2020 will feature performances, exhibitions, talks and discussions, a Healing Space and The Marketplace, which connects cultures and communities from around Australia and across the Pacific, including this year's invited country Canada.

"The commitment and vision of WOW aligns with my Government's Queensland Women's Strategy 2016-21 and our goal of gender equality across our State. And it is working," the Premier said.

"The message we're sending out to all women and girls is 'you'll have a fair go', and WOW Australia 2020 is helping to make these changes happen."
