MIDFIELDER Karl Amon becomes the 50th player to reach his 100 AFL game milestone at Port Adelaide on Friday night - and possibly could be an All-Australian soon after.

Six years after his AFL debut coming on as the sub against Brisbane - and after overcoming the challenges posed in playing just six AFL matches in 2018 - Amon has become one of Port Adelaide's critical pieces in the midfield with his game-breaking run, piercing left-foot kick and increased appetite for inside football.

And the key to success remains with a focus on the team's needs, even when the moment comes to take a bow at a milestone.

"In reflecting this week, (100 games) means a little bit - and post career, looking back, it will be something I am really proud of," Amon said. "I am certainly proud this week of reaching 100 games and, hopefully, there are many more to come.

"There was one year (2018) when I didn't think I would get (to the 100-game milestone at Port Adelaide). It has been spoken about enough now and I have really loved the past three years that I have had here. 

"I have not missed many games and I have been building my game around a strong group that we have here.

"I felt I had it in me, but it has taken the past three years to gradually build my form. The year I have had this year is quite pleasing with self-satisfaction. But I am still not happy with where I am; I want to continually grow my game and be the best footballer that I can be.

"(All-Australian) isn't something I am looking at nor worried on. The focus is on team success. We are coming into the good part of the year when you want to be playing good footy - finals footy.

"If you form is recognised (by the All-Australian selectors) it is something you can look back on and be proud of. But I am still wanting to build my game and improve where I can ... by building my inside game which has helped me a lot this year.

"As a group, we are looking for that team success - that is why you play football. That is what we are building to. We were six points off a grand final last year (by the home preliminary final loss to eventual premier Richmond). If we can go further this year, it would be amazing."

Amon, 25, arrived at Port Adelaide as the No. 68 pick in the 2013 AFL national draft - and as the pin-up boy for those overcoming Perthes disease that kept him on regular visits to hospital from the age of five to eight and in a wheelchair and on crutches between operations.

"I have tried to be an inspiration for young kids who have had Perthes," Amon said. "If I can reach out to anyone who has suffered Perthes or families.

"Once I was drafted to the AFL I felt I had achieved a goal and to reach 100 games is amazing."

Amon's milestone match is built in a Friday Night Football game loaded with huge team  objectives - such as a top-two finish with the right to two home finals at Adelaide Oval month. The opponent, the Western Bulldogs, has its own top-two aspirations, setting up a pseudo finals before the finals.

"We spoke about that straight after the game (against Carlton on Saturday)," Amon said after training at Alberton Oval on Wednesday. "(The Western Bulldogs) are a quality outfit and have probably been the No.1 contender for most of the year. 

"It is a mini-final for us.

"We have built that connection within the playing group - and the coaching group as well. We are a pretty young team and the experience we had last year in playing finals is really going to help us. We can reflect on what happened last year and, hopefully, grow from that going into this year's finals series.

"We can certainly learn from last year ... it is good we all had a taste of finals footy and everyone of those boys in the locker room is really hungry for what is going to come."

Port Adelaide's record against top-four contenders this season becomes part of a sharp debate during next month's finals. The scorecard against the other four teams still in the hunt for a top-four finish to the home-and-away season reads: Lost to Brisbane at the Gabba by 49 points in round 7; lost to the Western Bulldogs at Adelaide Oval by 19 points in round 9; lost to Geelong by 21 points at home in round 13 and lost to Melbourne at Adelaide Oval by 31 points in round 17.

"We have been building in the past month," says Amon of the form Port Adelaide has had while regaining key players recently. "To knock off a team of (top-four) calibre on Friday night would be massive for us; just to build that momentum going into finals would be huge."

The scoreboard returns to 0-0 in any finals match-up with any of these premiership rivals. But where would the confidence meter be with the Port Adelaide players?

"Internally, we have had that confidence that we are playing good footy," Amon said. "There is still room to improve, but for the past three weeks we have been building by getting back certain players who complement our game.

"(Winning against a top-four side) would certainly help (confidence). If you come into finals knocking off the Western Bulldogs, after they have been in the top two for most of the year, it is certainly going to help build your confidence. We have been building and growing over the past month - to get that (top-four) scalp would certainly help."

On the injury front, Port Adelaide has lead ruckman Scott Lycett (right knee) and key defender Trent McKenzie (hamstring tightness) available for selection.

"Scott moved on the track pretty freely, so I expect he would play," Amon said. "Trent had a little hiccup in training last week, but he was moving around today and is good to play."

Port Adelaide will fly-in, fly-out with a charter flight to and from Melbourne to maintain COVID protocols set by SA Health. The squad will leave Adelaide on Friday and return after midnight.

Amon, a member of the AFL Indigenous advisory committee, described recent racial slurs of AFL players - including team-mate Aliir Aliir after the recent Showdown - as "pretty challenging" for him.

"It touches the heart a little bit," Amon said. "It has been pretty tough. 

"The competition lately has been very good at calling stuff out. As a playing group, we are sick of it. We are in 2021 and it is still happening today ... the sooner we put an end to this, the better. 

"The more it happens, the more it builds up inside of yourself and as an Indigenous group of players we are sick of it. The sooner we can educate people, the sooner we can move on - the AFL will be better and future Indigenous players will feel more comfortable coming into the system."
