According to an investigation by the AFL Fans Association, clubs have repeatedly made it harder for fans to attend games over the course of the 2017 season courtesy of the current dynamic ticketing policy.

The system was introduced at the beginning of last season in order for clubs to increase or decrease ticket prices, but only by a small amount at any one time ($1-$3).

Most clubs have however chosen to increase prices, with 51 of the 56 instances in which dynamic ticketing has been used leading to a price hike.

The Saints, Tigers and Cats have all increased prices a staggering seven times this season, while the Bulldogs have done it on six separate occasions.

Only Sydney (twice), and Collingwood, GWS and St Kilda (all once) have decreased their prices this season, while Adelaide, West Coast, Gold Coast, Port Adelaide, Brisbane and Melbourne have all stayed away from the system, and haven't used the method once all year.

AFL Fans Association president Gerry Eeman told Fairfax Media they were very pleased with the clubs who have avoided using the system altogether.

"Our praise goes to all clubs who don't exploit their fans through dynamic pricing," Eeman said.

"We save particular high praise for the Demons, who are the only Victorian club not to have used dynamic pricing to increase ticket prices.

"Certain clubs are using dynamic pricing to gouge fans who do not have a reserved seat membership.

"The system simply makes it more expensive to buy reserved seats and is incredibly confusing.

"Furthermore, dynamic pricing affects members. If you have a general admission membership and you want to or need to reserve a seat, most clubs will make you pay the dynamic price increase applicable to the seat you select."

The investigation found a number of interesting examples of dynamic ticketing being used, with the Hawks seemingly stinging their fans more than most sides when they do in fact implement the system.

In round five against the Eagles at the MCG, they increased eight of nine categories by $1-$6 and drew a crowd of just 28,997, while in round 12 against the Suns at the MCG, they increased eight categories again by $1-$5, with a crowd attendance coming to 27,392.

Incredibly, North Melbourne priced their level two seats against the Saints in round 13 at $87, with a crowd of just 26,107 turning up on the Friday night, after they increased four categories by $9 each.
