A junior Australian Rules football coach charged with child grooming has been granted bail on the New South Wales mid north coast.

Mark Heaney, 42, was arrested at his Coffs Harbour home yesterday afternoon, and his phone and computer were seized.

Child exploitation unit detectives posed as a 13-year-old boy and had online conversations with the football coach after a local family said Heaney had inappropriate conversations and sent explicit images to their son.

Heaney winked at his family when he was brought into the Coffs Harbour courtroom.

His father has agreed to pay a $10,000 bond, and the internet will be disconnected at the home while Heaney is living there.

Heaney's bail conditions require him to avoid places or work that might bring him into contact with children under 16.

The matter is due back in court in July.

The New South Wales branch of Australian Rules Football is holding a public meeting tonight to address the issue.

AFL New South Wales and ACT General Manager, Tom Harley, says the first concern is to provide support for the community.

"Look it's obviously very shocking and it's all very raw at the same time," he said.

I've been in discussions with the police since last night and have been on the front foot to get across as much detail as possible."
