The 2002 European Championship in Frantschach-Sankt Gertraud was Abart's first international championship in the general class. She prevailed against Irene Mitterstieler in the team's internal qualification and took fourth place in the competition. From the 2002/2003 season , Abart started in the World Cup . In her first World Cup race, the parallel competition in Völs on December 21, 2002, the then 17-year-old was the youngest member of the field and only had to admit defeat to her compatriot Renate Gietl in the final. Also in her second World Cup race on January 11, 2003 in Umhausen , she reached second place, with which she briefly took over the World Cup lead. In the further course of the season, however, they could no longer follow these results. She only contested two World Cup races and finished eighth in the overall World Cup, tied with Austrian Sabine Kogler . At the European Junior Championships in Kreuth she won the silver medal, but only came in tenth at the 2003 World Championships in Železniki .
After that winter, Abart took a year off to find new motivation. In the 2006/2007 season she returned to the competition and was among the top five in five of six World Cup races, but only once as third in the penultimate race in Moos in Passeier on the podium. Like two years before, she reached fifth place in the overall World Cup. At the 2007 World Championships in Grande Prairie , she did not come close to her World Cup results and was only ninth. In addition, she took sixth place in the team competition together with Florian Breitenberger , Martin Psenner and Johannes Hofer . After the season, Abart finally ended her career.
