ADELAIDE and Port Adelaide could share about $11 million in additional revenue over the next three years after signing a new stadium deal at Adelaide Oval.

Following a review of the financial model that distributed income in the stadium's successful first season, the SANFL, Crows and Port Adelaide have all agreed to a new deal covering the next three years.

The agreement provides the AFL clubs with new revenues and inventory to enable them to share an estimated additional $3.1m in 2015, rising to $4.1m in both 2016 and 2017.

The deal rewards the two clubs with a higher return for bigger crowds.

It will also provide the Crows and Power with additional reserved seating income and corporate facilities; provide incentives for playing home finals, and protects the SANFL’s ability to drive game development in South Australia.

SA Football Commission chairman John Olsen said the agreement was "a good outcome" for all parties.

"We now have an agreement that delivers the lion's share of the uplift from the move to Adelaide Oval to the two AFL clubs, while also protecting the SANFL’s ability continue to develop the critical pathways to elite football in South Australia," Olsen said.

"This has been an exhaustive process but it's a complex model and we had to ensure we got it right. We are now in a position where football in South Australia has a springboard for the future."

Port Adelaide chairman David Koch said the club was delighted with the support of its members and fans at the new stadium.

"Port Adelaide is looking forward to continued strong support from fans and members at our games in 2015, and we are pleased that this support will translate into solid financial returns for our club,” Koch said.

Adelaide chairman Rob Chapman said the length of the review reflected its importance, while the outcome brought positives for all parties.

"Our loyal members and fans have taken their support to another level since we arrived at the new stadium, and we were compelled to achieve the best possible outcome to ensure the club continues to prosper," Chapman said.

AFL CEO Gillon McLachlan said the deal would provide a fairer distribution of the financial spoils produced by the new stadium's success.

"The new arrangement agreed today is a win for South Australian football, providing a fair share of revenue from the success of the new stadium to the clubs and to local football," he said.

"Without the foresight of the State Government and the passion of South Australians for both football and cricket, our competition would not have this world-class facility."
