Queensland Labor MP Brittany Lauga has alleged she was drugged and sexually assaulted in the central Queensland town of Yeppoon last weekend.
In a statement posted on social media, Ms Lauga said she had contacted police in the early hours of Sunday morning.
"Tests at the hospital confirmed the presence of drugs in my body which I did not take. This substance impacted me significantly," she said.
The member for Keppel also wrote that throughout the week she had been contacted by several other women with similar experiences from the town.
"This could have happened to anyone and tragically, it does happen to many of us," she said.
"It's not ok. We should be able to enjoy socialising in our town without the risk of being drugged or assaulted."
The Queensland Police Service has confirmed it is investigating a sexual assault complaint relating to an incident in Yeppoon last Sunday.
Queensland Premier Steven Miles said the government is supporting Ms Lauga in any way they can.
"No one should have to go through what Brittany is going through," he said.
"My sole focus is on Brittany and her wellbeing. I've told Brittany that we're here to support her, whatever she needs."
Queensland Housing Minister Meaghan Scanlon said the statement made for "difficult reading".
"Those are shocking allegations … I understand that Brittany is going to take a short time to look after herself and we absolutely support her to do that," she said.
