Griggs has been at the Seven Network since 1993 where she joined Seven Sport, first as a host at the Australian Open. She hosts the network's Olympic Games, Commonwealth Games and the Australian Open, as well as being a presenter of their Melbourne Cup coverage. She has been the host of Better Homes and Gardens since 2005 and House Rules from 2013 until 2019.
In winning the 50-metre backstroke race at the Australian Swimming Championships in 1993, Griggs recorded the fastest time in the world (that year) for the event. The day following that swim, she announced her retirement from competitive swimming.
Her career was cut short after a battle with chronic fatigue syndrome that began when she was 17. She had previously attempted a comeback in 1992, however, the exertion of that comeback hospitalised her with pleurisy, and ultimately caused her to withdraw from the 1992 Olympic trials.
Griggs was the first guest on the long-running ABC programme Live and Sweaty. As part of the programme, sporting guests were asked to donate various body parts to the "Sporting Hall of Fame". Griggs donated her appendix.
Griggs built a solid career in media, and in the late 1990s was a regular panelist on the Network Ten program Beauty and the Beast. At this time she was also dating rugby league footballer Luke Ricketson.
Griggs hosted several seasons of lifestyle type shows, including Auction Squad and House Calls to the Rescue. She participated in the Australian Open coverage, and was the first Australian woman to solely host an Olympics coverage when she covered the 2002 Winter Olympics in Salt Lake City.
In 2009, after previously acting as a fill-in presenter for Seven News Sydney weekend sports bulletin, she took on the role full-time, replacing Alex Cullen, who moved to the weeknight role. In November 2010, Griggs resigned from Seven News to spend more time with her family.
Griggs, who was previously married to actor Gary Sweet, has two sons.
