The Mandurah Makos Masters Football Club will rally for a cause close to their hearts when they host their annual Amber Field Memorial Day this Sunday.
Devastation hit the club when the four-year-old daughter of player Tim and his wife and Makos member Kirstin lost a lengthy battle with congenital heart disease in August 2017, but they've made it their mission to carry on her spirit and raise funds for children's charity Heartkids.
The organisation, which stood by Amber's side as she endured surgeries and long stints in hospital, will be at the forefront of the day as over 1000 people from 16 clubs converge on Rushton Park.
It will be the second annual Amber Field Memorial Day the club has held following the success of their inaugural event last year, which raised more than $3000 for the charity.
It's a cause that bears weight throughout the entire Makos club, which rallied around Tim, Kirstin and their sons Patrick and Daniel in their darkest hours.
That support remains overwhelming to Kirstin.
"The club was so helpful the entire time Amber was going through [her battle]," she said.
"Just to have people like that to lean on, people close to us who were huge emotional supports, it meant so much to us.
"Amber loved the club. She loved spending time here and they went through it all with us, so to still have that support now and to be holding the fundraiser again, it's amazing.
"We can't say enough for Heartkids, too. They connect you with families who have been through the same ordeal and they just do what they can to make it less stressful.
"The memorial day is a way to say thanks for that support - it's just a special day for everyone involved."
Makos president Tony Wilkey said the day would be used to spread a message as much as raise funds for the charity.
"Just making people aware of the organisation and showing those who might be going through a similar situation where they can get help is just as important as raising the money," he said.
"We saw what Tim and Kirstin went through and as a club we felt it too, so to be able to help them out using our home round is really important to us."
The day will see more than 32 teams from Masters clubs across the state descend on Rushton Park's three ovals, with the first games kicking off around 9.30am.
