Ministers rally behind Queensland Labor MP who was allegedly ...

Police are investigating after a Queensland state MP was allegedly drugged and sexually assaulted last weekend, with the premier offering his support.

Brittany Lauga, the assistant minister for health, said she reported the incident to Yeppoon Police in the early hours of April 28.

Lauga alleges she had ingested a substance without her consent, which impacted her "significantly".

"I went to the Yeppoon Police Station and Yeppoon Hospital, after being drugged and sexually assaulted," she said via social media.

"Tests at the hospital confirmed the presence of drugs in my body which I did not take. This substance impacted me significantly."

Queensland Premier Steven Miles said the government was there to support her, whatever she needs.

"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."

Lauga said she had been contacted by other women who may have also been drugged in Yeppoon, about 38 kilometres northeast of Rockhampton.

"This could have happened to anyone and tragically, it does happen to many of us," Lauga said.

"I have had multiple women contact me who have experienced the same thing in our town.

"We should be able to enjoy socialising in our town without the risk of being drugged or assaulted."

Lauga requested privacy in the post, saying she needed time to "physically and emotionally heal".

"Thank you to everyone who has reached out to me in support. I truly value your thoughtful messages, gestures and kindness.

"If you have any information that may assist the investigation, please tell the police."

The Queensland Police Service said they are investigating a "sexual assault complaint relating to an incident in Yeppoon".

"Investigations into this matter are ongoing. As is routine in such investigations, no further comment will be made at this time."

Queensland Housing Minister Meaghan Scanlon said the allegations were shocking.

"I've read Brittany's statement and it's really difficult reading."
