Police raided two Caloundra homes on Sunday, allegedly finding a video of an unknown woman showering in a public toilet block at Kings Beach, in Caloundra.

The man has also been charged with recording a woman showering in her Caloundra home on April 24 and an "upskirting" incident at a Caloundra shopping centre on October 30.

Police are calling on anyone with information, especially women who believe they may have been filmed, to come forward.

Sunshine Coast Criminal Investigation Branch officer-in-charge Senior Sergeant Daren Edwards said the investigation was ongoing as police continued to analyse the seized property.

"I would ask any woman who used the showers at Kings Beach, Caloundra on April 29, between the hours of 8am and 5pm, who thought they may have been observed, to contact Policelink on 131 444 or Caloundra CIB on 5439 4406," he said.

"I would also appeal to anyone who believes that they may have been a victim of offences such as 'upskirting' or illegally having their image taken in circumstances such as this on the Sunshine Coast, to contact us."

The 25-year-old is facing three counts of making observations or recordings in breach of privacy and is due in the Maroochydore Magistrates Court on Monday.

He was also charged with possess drug utensil and possess property suspected of being used in a drug offence following the raids in Minchinton and Widgee streets in Caloundra.
