The top-order batsman spent the 2003 summer playing for Northamptonshire with a British passport and ended the season as one of the most prolific run scorers in the country, but was told he was surplus to the county's requirements for the following year.
He was re-branded as an overseas player for the 2004 season with Yorkshire after playing for New South Wales in the Australian domestic season.
Yorkshire employed him as a replacement overseas player whilst Darren Lehmann was on international duty and he repaid their faith in him by plundering over 1,000 first class runs in the 11 games he played.
He returned to Headingley in 2005 and was the first Yorkshire batsman to reach 1,000 first class runs.
He did so during his innings of 219 in the County Championship match against Derbyshire at Headingley, when he put on 310 with Anthony McGrath for the third wicket.
It was a county record for that wicket against Derbyshire, beating the unbroken 293 between Ashley Metcalfe and Phil Robinson at Scarborough in 1990, and it fell only 14 short of becoming a new record for Yorkshire against any county.
He ended the season with 1,359 county championship runs at almost 65 as Yorkshire won promotion before it was announced that he had signed a two-year contract with Worcestershire.
His fine form continued for New South Wales when he returned home for the winter and he was rewarded when he was named in Australia's 12-man squad for the second Test against South Africa in Melbourne and was later called-up to the Australian squad for the VB Series.
He made a stunning impact with 94 against South Africa, the highest score by an Australian on debut after having to introduce himself to captain Ricky Ponting and has now played in two Tests.
Jaques continued to score runs for fun in 2006 at Worcestershire. He finished with 1148 county championship runs at 88 with a top-score of 244 but despite this he did feature during the 2006/7 Ashes due to Australia's embarrassment of riches.
