PORT Adelaide defender Hamish Hartlett has supported the notion of playing all round 23 games at the same time.

Former Power premiership-winning coach Mark Williams raised the idea as a way of building suspense during the last round of the season.

Simultaneously playing games is a concept used in soccer competitions around the world, including the English Premier League and the FIFA World Cup, to prevent teams manipulating results.

Hartlett said the idea had merit and would keep supporters on the edge of their seats.

"That would make things pretty interesting and add another dynamic to the end of the season," he said.

"I like it, that's the first time I've thought about it.

"Off the top of my head it sounds like a pretty good idea.

"I'm sure there's reasons we're not doing it at the moment, but it sounds all right to me."

The AFL is locked into the current fixturing arrangement until the end of the broadcast deal in 2022.

Logistically, it would also be a challenge, with the MCG and Etihad Stadium only able to host one game during the round.

However, part-time venues like Mars Stadium in Ballarat and UTas Stadium in Launceston could be used to accommodate home games for the Western Bulldogs and Hawthorn respectively.

Williams told Melbourne radio station SEN that competitions such as the EPL have showed it can be successful.

"It's not good for the media, I understand, but everyone gets used to everyone playing at the exact same time," Williams said.

"Therefore, people can't contrive or know what percentage they need to get to get into a higher position or into the finals or top-two or top-four.

"If everyone is playing at the same time, it's pretty equal.

"It at least gives everyone a fair chance without prior knowledge."
