Former World Champion Rachael Grinham is one of the most recognisable names on the PSA World Tour with a lengthy career that has seen her win some of the biggest prizes that the women's game has to offer.

She showed her pedigree from a young age, winning the World Junior Championship at the age of 16, before she breached the world's top 20 four years later. Her first Tour title came at the Toulouse Open in 1998 while she defeated Malaysia superstar Nicol David in the final of the Milo National Open.

2001 saw Grinham break into the top ten in the World Rankings and she participated in the first family final ever on the Tour, defeating sister Natalie to claim the Kuala Lumpur Open title. Two years later, Grinham won the prestigious British Open for the first time by defeating Cassie Jackman in the final and she retained the title in 2004 while rising to the World No.1 spot.

Grinham was superb in the 2004/05 season and kept her World No.1 ranking for 16 consecutive months. She faced heartbreak though in the 2005 World Championship final as she fell to Nicol David after beating her sister in the semi-final. 2007 was Grinham's finest year as she gained revenge on David in the final of the British Open, coming back from 2-0 down to lift the event for the third time. Shortly afterwards, she bested her sister yet again to win the World Championship for the first time.

Injury struck later on in her career as she missed a large portion of the 2010/11 season through injury as she slipped out of the world's top five. She lifted the Victoria Open in 2013 and the Women's Squash Week and Caboolture Open titles followed a year later. She narrowly missed out on retaining the Women's Squash Week in March 2015 but she lost out in the final.

Grinham secured a number of semi-final appearances throughout the rest of 2015 at the Texas Open, Australian Open and Monte Carlo Classic. The Australian fell out of the world’s top 20 for the first time in the February 2016 World Rankings since 1997.

She reached the quarter finals of the HKFC International later that year, but did not make another semi final until 2018. That came at the Calgary Squash Week Open, where she was beaten by Danielle Letourneau. She also made the semis of the Queensland Open, Monte Carlo Classic and the Chief of the Air Staff International Women Squash Championship.

Grinham’s only title in the last four years came at her home tournament. She won the Australian Open in 2017, beating Sivasangari Subramaniam. She made two finals the year after, but was beaten on both occasions. Christine Nunn got the better of her in the NT Open, while the Tasmanian Open was won by Low Wee Wern.

Grinham went on to reach the quarter finals of the Calgary CFO Consulting Services PSA Women’s Squash Week in 2019, before then making the last four of the J Warren Young Memorial Texas Open a couple of weeks later.

The former World No.1 reached the last 16 of the DPD Open and J.P. Morgan China Squash Open in 2019, but was unable to make it through to the third round of a major event in 2020. Her first appearance of 2021 saw Grinham make the quarters of the Sandgate Open on home soil in Australia.
