RAA will give one lucky supporter $10,000 every time Port Adelaide's home crowd reaches 50,000. 

The prize will celebrate Port Adelaide reaching its 60,000-member target ahead of Round 6's game against West Coast at the Adelaide Oval.

As Port Adelaide's official membership partner, RAA wants to help keep the Power's current record average attendance figure going for the rest of the year.

RAA general manager of sales and marketing Tom Griffiths said it made sense to offer the reward every time Port Adelaide packed the house at the Oval.

“Membership is at the heart of everything we do at RAA and this focus is certainly something we share in common with Port Adelaide,” Griffiths said.

“Reaching 60,000 members is a fantastic achievement and RAA is delighted to support Port Adelaide in encouraging members and supporters to get to the club’s remaining Adelaide Oval games this season.”

The cheque for $10,000 will be awarded to one randomly selected fan at the ground when the official attendance figure exceeds 50,000 at three-quarter time of Power home games.
