A passerby said about 9am there were three marked police cars at the property near the intersection of State Highway 1 and Phosphate Rd at Clarendon.
Traffic was still flowing but there were two officers in armed offender squad-type uniforms about 30m south of the entrance of the house at the property, he said.
The raid was in relation to a pre-planned search warrant, a police spokeswoman said.
"Everything’s under control, everybody’s fine," a police officer at the scene said.
