Hawthorn key defender Tegan Cunningham is free to play in Saturday's clash with Port Adelaide after overturning her one-match ban at the AFLW Tribunal.

Cunningham was reported for a bump on West Coast's Charlotte Thomas in the final quarter of Hawthorn's dramatic win over the Eagles last Friday.

The incident was assessed as careless conduct, medium impact and high contact, drawing a one-match ban.

Cunningham's first line of defence was there was no head-high contact at all.

As a back-up argument, Cunningham's lawyer Myles Tehan argued the impact to the head should be ruled negligible or low, instead of medium.

Cunningham gave evidence in which she continually insisted her shoulder didn't make contact with Thomas' head.

"I got her across her delts and the front of her pec region," Cunningham said.

"I felt no contact with the head or neck region."

Her argument was successful, with Tribunal chair Renee Enbom saying she wasn't satisfied high contact had been made.

The result means former basketballer Cunningham is free to face Port and she might be matched up on Power star Erin Phillips at times.

Adelaide's Jess Waterhouse accepted a one-match sanction for striking Port Adelaide's Amelie Borg.

West Coast's Aimee Schmidt accepted a reprimand for rough conduct on Hawthorn's Isabelle Porter while Gold Coast's Serene Watson received a reprimand for a dangerous tackle on Richmond star Monique Conti.
