At lunch, Australia, leading by 35 runs from the first innings, reached 163 without loss with Jaques unbeaten on 78 and Katich not out on 74 on the third day of the Test at Kensington Oval.
Australia continued from their overnight total of 35 without loss, and the two openers capitalised on the easier nature of the pitch and dropped anchor, as West Indies only seemed to be only going through the motions.
Neither Katich nor Jaques offered a chance, and everything West Indies tried, they seemed to find a method to counter it.
Katich chopped his 107th delivery from West Indies captain Chris Gayle - trundling his uncomplicated off-breaks - to square third man for two to reach his 50.
Jaques soon followed his lead and guided his 124th delivery from left-arm spinner Sulieman Benn to backward point for two to reach his landmark.
Australia lead the three-Test series 1-0, after they won the opening Test at Sabina Park in the Jamaica capital of Kingston by 95 runs.
The second Test at the Vivian Richards Cricket Ground in the Antigua village of North Sound was drawn.
As a result, the Aussies have already retained the Frank Worrell Trophy.
