A Queensland police officer acquitted over a Palm Island death in custody is facing assault charges.

Senior Sergeant Chris Hurley, 47, has been charged with two counts of assault after allegedly pushing an on-duty female officer at Robina Town Centre on the Gold Coast last month.

He is also facing a charge over a third matter that "relates to conduct not related to the workplace", police say.

Sen Sgt Hurley is due to appear in Southport Magistrates Court on March 15.

In 2007, he was acquitted of the manslaughter of Aboriginal man Cameron Doomadgee, also known as Mulrunji, on Palm Island.

Mr Doomadgee died on the north Queensland island in 2004 shortly after being arrested for swearing.
