In 2003 Bondarenko tried to qualify for the main draw of the WTA tour, but failed in Hobart, Melbourne, and Hyderabad. She then made it through her first WTA Tour main draw as a direct entry at the Copa Colsanitas, but ended up losing to Flavia Pennetta in the very first round 3–6, 1–6. She then went back to the ITF circuit after failing to qualify in the Abierto Mexicano Telcel but was unsuccessful, only making it through one semifinal in Taranto out of seven events. She also failed to qualify for the French Open and Wimbledon. In the middle of the two Slam tournaments she made the quarterfinals of the ITF events in Galatina and Fontanafredda. She then once again tried to get through the main draw of the WTA Tour but failed each time including the US Open. Following the US Open she won her second ITF title in Zhukovskiy.
