Police are searching an area at Mt Morgan, south of Rockhampton, for any sign of a missing central Queensland couple.

Chantal Barnett, 27, and Robert Martinez, 26, have not been seen since late February or early March.

Detective Senior Sergeant Scott Moon says Rockhampton police launched the search after a tip-off from the public.

"We're conducting a search in the Mount Morgan area around the Tipperary Road," he said.

"The information is something that we're very thankful for the public for providing us today.

"We've put the SES up there co-ordinating the search, and we'll continue that search until we're satisfied that the area has been cleared."
