Bradley Hill walks into the St Kilda changeroom on Saturday, but he is not alone inside the game-day sanctuary.

The Noongar man is accompanied with daughter Harriet while heavily pregnant wife Sammy is in tow with their first son just days away from birth.

Hill's three-year-old Harriet soon spots her favourite Uncle approaching, however he's no Elder.

She jumps out of her dad's arms and with her arms extended out, coach Ross Lyon leans down and gives her a hug.

Harriet adorably grabs Lyon's hand and Hill grabs her other, and the Saints leaders walk her into another pre-match room much to the amusement of St Kilda club staffers.

Stephen Hill, the retired 218-game champion for Fremantle, comes in a bit later to share the special day, handing over his young brother's guernsey in a presentation in front of teammates and club onlookers.

The extra faces present, all close to Hill's heart, are there to commemorate a remarkable 250 AFL games.

Hill's career climaxed inside the first 75 of his 95 appearances for Hawthorn on the back of the 2013-14-15 premiership sides before a return to Western Australia had the winger play out an additional 54 matches for Fremantle under Lyon the first time around.

But at St Kilda, the 31-year-old has found a permanent presence, and a purpose, after Lyon rejoined the club last year.

Hill played his 150th AFL match – in his debut appearance for his new club – his 200th and his 250th all for the Saints while now amassing 100 appearances for the club.

After re-signing a new three-year deal with St Kilda last week, Hill is set to play out his next 300th-match milestone and play more than half of his AFL career games for the Saints.

"Bradley is the kind of player who could play the next day," Lyon told others in a pre-game speech of Hill.

"His body responds so well to elite preparation."

The Saints then run out onto the oval and Harriet is carried onto Hill's right arm and shoulder.

After they break through the team banner, she quickly spots vision of herself and dad on the scoreboard and is left pointing and laughing at the very sight.

The smile refuses to come off her cheeky face before Hill's Noongar/Wajuk and Walmadjari teammate, Liam Henry, blatantly accelerates past the pair just to high-five Harriet to get one last reaction.

She grabs the attention of Nasiah Wanganeen-Milera and Zak Jones as the players attempt to stretch in the warm-ups while amusing Hill's daughter.

Lyon is back out before the first bounce of St Kilda's match with West Coast, and he gawks at the TV monitors during an interview, views vision of Harriet and for an AFL coach sheepishly says, "I'm just cuddly Ross to Harriet," he smiles.

Lyon talks more about what effect Hill has played on the hard-edge coach.

"He's built a great career on the field and a beautiful one off it," he says.

"But he's also been a special part of my coaching journey.

"First of all, his brother Stephen was an absolute star, as is Brad, but in our last meeting, we played vision to the group of him on the biggest stage, a three-times premiership player, just relentless, but also a sacrificial runner.

"His epitaph, what's on his footy tombstone, I think he'll be pretty happy with it."

Hill played out the 250th match in good form, with 10 kicks, eight handballs and plenty of runs up and down the wings that summed up his football longevity.

But it was his last kick of the day from one of his two marks that stung a bit of curiosity of what Hill was thinking.

The long kick had the ball just outside the 50m mark in the dying minutes of the 72-point win, but elected not to give in to Saints fans' wishes and bomb it long for a memorable goal.

"I actually said to Riley Bonner, 'Should I do a torp?' and he was, 'Maybe just go a drop punt' and then I saw Ro(wan Marshall) lead out, so I thought I'd better do the team thing," Hill said.

The Eagles' defence that was powerless to stop 17 earlier goals, including seven in the last quarter, was able to get a hand in to prevent Marshall marking Hill's pass, leading the popular figure to regretting his decision.

"I wish I did the torpedo now," Hill laughed, "I wish I could take it back."

Hill cherished being the centre of attention around a club that adopted during St Kilda's huge 2019 off-season trading.

The club was determined to win the contest for their eldest player after Hill lost both previous milestones for the Saints, but also admitted he was relieved it was finally all over.

"The build-up has been pretty exhausting this week – even today to be honest to have the little one (Harriet) in there before the game," Hill said.

"She wanted me to latch on and I was concentrating on my prep a little bit.

"It was awesome to have her out with me and we've got another one on our way this week.

"It's great memories for us to have her run out with me for the years to come."

Hill, reflecting on his career briefly, was full of praise for Lyon, adding that the coach has always backed in his abilities and is the key factor behind having the faith of playing until he's at least 34.

"Ross has always been someone I can lean on," Hill said.

"You can have a lot of open conversations with him because I respect him so much.

"I look up to him a lot and he's really helped me out a lot, and has always been there for me.

"Even when I left Freo in the gap when he wasn't coaching, I still had him there and he was always close to me."
