The Manjimup police station had the last laugh after a woman seemed to have fobbed off an unwanted suitor by handing out the station's number instead of her own.

The south-west police station took to Twitter on Sunday to share the joke, saying the woman's trick had given them "the giggles".

Constable Tim Jones was on duty when he received a text message starting with an unassuming "Hi", to which he replied "Hello this is the Manjimup police, can we help you?"

The request for help was declined and Constable Jones left the scorned suitor with the encouraging words "better luck next weekend."

"He asked me a few more questions after that, asking me to prove that I'm the police," he said.

"He must have been pretty disappointed."
