The Greens want kids out there kicking balls, getting fit and having fun.
Redlands Greens candidate Carmen McNaught said the $500 million Greens Free Sport for Queensland Kids initiative would replace a similar scheme and was aimed at helping parents on a minimum wage.
It would be funded by a 0.05 per cent levy on banks.
"Under this proposal the government will guarantee all Queenslanders under 18 a free season of organised sport every year by covering all registration costs, paid directly to clubs," Ms McNaught said.
"The average cost of a season of club sport in Queensland is $775 per year, which means a family with three children could end up having to pay over $2000 just so every child can play.
"That's just too expensive for too many families.
"Just like health and education, sport is an essential service and it should be the birthright of every Queensland kid to play organised sport, regardless of their parents' ability to pay.
"Organised sport is crucial for children to get fit, make friends, have fun and learn new life skills."
Ms McNaught said spending money on sport would boost the state's economic recovery by injecting hundreds of thousands of dollars every year into the thousands of registered clubs.
"It will be cheaper to administer and fairer than the complicated current system of sport vouchers which covers only 20 per cent of club sport, and is available to parents with a low-income card, which means hundreds of thousands of parents doing it tough on the minimum wage can't apply," she said.
The Greens will also provide $10,000 grants to sports clubs to help upgrade facilities, recover from the impacts of COVID-19 and handle the extra registrations that will come with free sport, and give parents a $150 rebate to buy of sports equipment.
"The cost of $500 million a year will be covered with a 0.05 per cent levy on the big banks," she said.
"Our plan will produce massive cost savings on mental and physical health that will come with more kids playing sport. This plans is good for everyone - kids, families, the community and the economy."
