A familys wishes have come true after an inspirational search for a bone marrow donor for Darcy Keeley, four, uncovered a match.

The young Perth boy was diagnosed in June with acute myeloid leukaemia, needing a bone marrow transplant.

Finding a match proved difficult and sparked the campaign Do it for Darcy.

His family took to social media, relentless in their pursuit to help their little boy.

When the story of the boy dubbed the little lion started to spread, thousands of people came forward to try to lend a hand.

Recently one of our most loyal, passionate and enthusiastic supporters, Darcy Keeley, was diagnosed with Leukaemia, requiring 6 months of intensive chemotherapy followed by a bone marrow transplant, Hamersley Carine Footy Club posted on GoFundMe in July.

On their campaign Do it for Darcy, the family explained he was in isolation in Perth Childrens Hospital.

He needs a bone marrow donation and currently the national and international bone marrow registry is yet to find one, they wrote.

Thousands of people rallied around Darcy and his family, signing up to see if they were a potential match to be a donor.

On Thursday, his mum Casey announced in a heartfelt social media post they finally had a match.

IT HAPPENED... guys it actually happened!!! We got the match weve been waiting for! she said.

Darcys transplant doctor confirmed yesterday we have stem cells from some cord blood!

This is a huge relief and allows us to focus on the next step to recovery.

She said an employee at Lifeblood said literally thousands of people registered to try to help Darcy.

Casey also added that the campaign had subsequently led to many new donors.

There have been literally THOUSANDS of ABMDR [Australian Bone Marrow Donor Registry] registrations and new donors as a result of our Do it for Darcy campaign, she said.

The mum said this would help people all around the world, adding they were proud of the awareness the campaign had created.

It is impossible to express our gratitude for all of you who have rallied behind us and registered to be bone marrow donors, donated blood products and spread the word, she said.

As parents, there is nothing more heartwarming than people supporting your child, especially in a time of need.

And the love we have felt wrapped around us [has] helped us as a family immensely.

The loving mother conceded that while they are only at the beginning of fighting this illness, this win will help them move forward.

She also encouraged people to keep spreading awareness.

This is not the end of the fight, Casey said.

Its really just the beginning.

The transplant process will be challenging, but for right now lets focus on this win.
