The Sydney Swans are being sued by a father and son over a sexual abuse case.

The incident dates back to 2014 when former coach, Mark Heaney, was involved with the club’s high-profile football Academy.

Heaney has already served jail time for the abuse. But now the Swans are looking at a multimillion-dollar legal fight.

The son launched an institutional sexual abuse action in the NSW Supreme Court in December last year and now the father has followed suit.

They are suing both Sydney and the former coach for their trauma.

The father says he is angry while the son — who cannot be identified for legal reasons — says his AFL “dream was shattered behind closed doors by people” he was taught to trust.

“I’m angry nobody from the Swans or the AFL ever had the decency to contact us and apologise or take responsibility or offer counselling,” the father told News Corp.

“I feel they brushed the abuse under the carpet.”

The son said the abuse took away “years” of his life and affected his health and “sense of safety in the world”.

“This case is about accountability ... healing, and making sure no other child ever carries this kind of silence.”

Lawyer Cameron Doig from Arnold Thomas & Becker is representing the father and son.

“This trauma significantly impacted the father’s relationship with his son,” Doig said.

“He has held in the pain for years, struggling with anxiety and trouble sleeping.”

Doig said the Sydney brand carried “significant community trust” and the father wanted “accountability from a wealthy and well-resourced defendant”.

Heaney, in 2014, pleaded guilty to using a carriage service to groom a child and spent 12 months behind bars.

A Sydney spokesperson said: “Heaney was employed on a casual basis from 2011-2013.

“As the matter is before the court, we are unable to offer further comment.”
