For the lucky ones, such as Port Adelaide's Willem Drew, they come around almost every 12 months.

The three-time Koroit premiership player will feature in his second SANFL decider in three seasons on Sunday, September 22.

The AFL-listed midfielder will don Port Adelaide Magpies' famous prison bars guernsey against either Adelaide or Glenelg at Adelaide Oval.

Drew, who has played 10 AFL games and 12 SANFL matches in 2019, arrived at Alberton Oval in November 2016 fresh from a hat-track of Hampden league flags.

He spent his first season as a Power footballer plying his trade in the state league before a foot injury wiped out his entire 2018 campaign.

Drew, 20, said he was excited to feature in a second SANFL grand final wearing the famous Magpie colours.

"I was in one my first year and we unfortunately lost by a point which was pretty frustrating and last year not playing footy at all was pretty annoying," he told The Standard.

"This year it's good to be in another grand final and we're all ready to go and hoping to win.

"I am nervous and excited. We have the week off so we have a bit of time to relax but I can't wait for next weekend.

"There is a really good bunch of blokes playing in the SANFL and we're all close mates so it's good to come back and play and we're just hoping we can succeed."

Drew said it was a relief to play consistently in 2019 after his foot surgery.

He made his AFL debut in round one and also finished the season in the Power line-up, collecting 22 disposals against Fremantle.

"At the start of the year I was actually pretty worried about how my foot was going to recover," he said.

"I had a few setbacks but with time it started to come good and to be able to put a full season together gives me confidence my body is going to hold up."

Drew averaged almost 16 disposals and 5.6 tackles a game for the Power.

The 190-centimetre midfielder said he was happy to play an inside role and was constantly looking for ways to entrench himself in coach Ken Hinkley's best 22.

"I was obviously nervous playing those games and when you're out there you don't feel very comfortable at all," he said.

"You're just trying to do your thing for the team and play your role and that's all the coaches keep saying to do."

Drew's home club, Koroit, will play in its seventh straight Hampden league grand final next weekend as it aims to make it six consecutive flags.

He played in three premierships (2014, '15 and '16), earning best-on-ground honours in the latter, before he was drafted to the Power.

Drew said it would be "unbelievable" if the Saints win again.

"I've been following along closely all year and I knew they were going along nicely," he said.
