Gold, Premium Gold and Platinum seats are still available, but are expected to be snapped up quickly in the lead up to the match.

With ticket allocations nearly exhausted, General Manager – Membership, Ticketing and Fan Engagement, Natalie Fagg encouraged Swans members to help fill the stands for the all-important match.

“It’s without a doubt one of our biggest games for the season,” she said.

“We want to see as many members at the match as possible to help create a fantastic atmosphere.”

Fagg also encouraged Swans members who are unable to attend Friday’s match to consider releasing their seat for purchase.

“We do understand that the Friday night timeslot doesn’t suit everyone, so if you have a reserved seat which you won’t be using, you can ‘release your seat’ and put it back for re-sale,’ she said.

“By doing so, your seat can be sold to another Sydney Swans fan, and you as a member will receive credits towards your 2015 Membership.”

The deadline to release your seat is Wednesday July 31 at 5:00pm. Click here to release your seat.

Friday night’s match will be the third-last home game for the Swans this season, with the club also set to host St Kilda at the SCG in round 21 and Richmond at ANZ Stadium in Round 23.

Fagg said fans interested in becoming members ahead of the finals series need to sign up before Thursday July 31.

“We have three home games left, so this week is the last chance for fans to take advantage of our Red 3 Membership,” she said.

“It’s the last opportunity to get on board, and we encourage fans to do so before Thursday because that’s the deadline to be eligible for finals benefits.”
