[4] Slatter made her selection debut for South Australia in 1992 in the state women's coxless four to contest the ULVA Trophy at the Interstate Regatta within the Australian Rowing Championships.
[7] In 1991 Slatter first competed at the national level with Megan Still when they contested the Australian women's pair championship title in an AIS composite crew.
All told Slatter won sixteen Australian championship titles for either South Australia or the Adelaide University Boat Club.
[9] Slatter's first Australian representative selection came at age twenty and straight into the senior women's squad for the 1991 World Rowing Championships in Vienna.
They made the Olympic final in the coxless four, a good result given their lack of international racing experience but finished in overall sixth place.
[11] With Snook and Dobson changed out for Courtney Johnstone and Gina Douglas, Slatter and Marcks stayed together in the coxless four into 1993 and they competed at the 1993 World Rowing Championships in Racice where again they were last in the A final and achieved a sixth place.
[12] It was a tremendous day for Australian rowing as the girls' gold medal was matched by the Oarsome Foursome of Ginn, Tomkins, McKay, Green and was supplemented by a silver medal from the men’s coxless pair making it the best day for Australian rowing at an Olympic regatta till 2008.
[12] Upon Marcks' 1996 retirement, Slatter was determined to go again and needed to find a new pair partner to build a campaign for Sydney 2000.
