Born in Serbia, Jelena spent her formative years in Australia after migrating to Sydney with her family in 1994.
She played her first three ITF events as a 14 year old but her breakthrough win came in 1999 when, as a qualifier ranked No.129, she defeated world No.1, Martina Hingis, at Wimbledon.
The following year she became the first Australian since Evonne Goolagong-Cawley in 1980 to reach the Wimbledon semifinals.
She was also an Olympic semifinalist that year in Sydney, losing to Monica Seles in the bronze medal play-off.
In 2001 Jelena won her first WTA Tour singles title and entered the top 10 for the first time. She changed her nationality to Yugoslavian (later to become Serbia and Montenegro) that year.
Jelena experienced a dip in form in 2004 and returned to Australia to rebuild her career under the Aussie flag in December 2005, winning the Australian Open Wildcard Play-off in 2006 and again in 2008.
The daughter of Liliana and Damir, Jelena has a younger brother, Savo. Her proudest career achievement is the No.4 ranking she peaked at in 2002, aged 19.
Off the court Jelena enjoys going to the beach, watching movies and shopping.
