The Great Aussie Rock Afternoon supporting Variety returns to the Redlands August 21 with a fun family day out.

The family event will be held on August 21 from 1pm, with more space, food trucks, kids activities, and a new stage to make it bigger and better than years before.

The charity event was postponed earlier this year with COVID lockdown which has limited the organisers' fundraising capacity since the pandemic began.

The Great Aussie Rock Afternoon was founded by Ormiston couple Steve and Sue Whittam in 2009 when they formed team Aussie Rock with 12 of their family and friends to support the children's charity Variety.

The event raises funds to help kids with significant life challenges.

Team Aussie Rock have raised more than $435,000 for Variety through several annual events over 12 years.

In November last year, 500 people went to the event. This year, co-founder Steve Whittam said he hoped to almost double the previous year's crowd.

"The aim is to reach at least 800 people attending the event. If this happens, we know we will exceed our fundraising targets," Mr Whittam said.

"So we ask all Redlanders to show their support, come and enjoy a fantastic afternoon, see some great entertainment and maybe win some great prizes. And don't forget to tell your friends who reside outside the Redlands...the more the merrier."

In addition to providing much needed equipment to help kids with challenges live their lives as normal as possible, they also fund ongoing scholarships for recipients approved by Variety.

Mr Whittam said it was rewarding to see the impacts of their efforts.

"Helping in this way means every dollar we raise goes to very specific needs...and the best part is, we get to see, first hand, the recipient of each project awarded and the positive impact it has on their life and those closest to them."

Some of the scholarships have been awarded to Tom Goldsworthy, Isabella Stanfield and William Martinelli, who will return to perform this year.

Tom, 17, is legally blind and autistic and will play the piano. Although he is partially deaf, he is pitch perfect and a talented performer.

Isabella, 13, has cerebral palsy and reads music in braille.

William, 18, was blinded as a result of a rare cancer but has not let this stop him from playing the guitar. He will take the stage with local band rock tribute band Aussie Pride whose members are committed to local fundraising efforts.

Lead bassist Steve Brewster said his band had raised more than $40,000 in five years.

"We have known the Whittam's and their efforts for some time now from when they come to see the band... we love what they do and it meshes so well with the bands philosophy on giving back to the community," Mr Brewster said.

"The 2020 event was such a fantastic afternoon...so much fun and we can't wait to perform at the new bigger and better show in August"

The Great Aussie Rock Afternoon will feature music on stage, a dance floor, food trucks, a sausage sizzle and activities for kids including face painting and a jumping castle.

Tickets are $20 per person - with free admission for kids under 17 with an adult - and can be purchased at the Grand View Hotel or phone 07 3884 3000.
