Network Ten's new true cold-case crime show, Wanted, is struggling in the overall ratings.

The three-week-old Australian series, hosted by Sandra Sully and Matt Doran, revisits unsolved crimes.

It launched on July 8 with 649,000 viewers giving it 22nd overall in the ratings, and the third episode on Monday pulled 518,000 to be the 25th most-watched show on OzTAM's overnight ratings.

From Ten's perspective the series is serving a purpose, stating that Wanted has lifted the network's average Monday night audience in the 8.30pm to 9.30pm timeslot by 22 per cent in total people.

However, on Monday Wanted finished a long way behind Hamish & Andy's Gap Year Asia (8-9pm), which won the ratings for the third straight week.

The comedy duo's antics pulled 1.455 million viewers to beat Nine News (1.409 million), The Block Sky High (1.393 million) and Seven News (1.337 million).
