Three Australians - Marc Polmans, Aleksandar Vukic and Ellen Perez - have made winning starts to their Roland Garros qualifying quests.
The No.31-seeded Polmans scored a three-set win against fellow Aussie Alex Bolt, prevailing 6-3 3-6 6-3 in a two-hour battle.
Polmans next plays 16-year-old French wildcard Arthur Fils, who eliminated Bernard Tomic in the opening round.
Australia's Aleksandar Vukic had little trouble against Portugal's Frederico Ferreira Silva, scoring a 6-3 6-1 victory in 61 minutes. The 25-year-old Vukic, who is attempting to qualify in Paris for a second consecutive year, fired seven aces and lost only eight points on serve.
In women's singles qualifying action, Ellen Perez overcame Russia's Vitalia Diatchenko in a close three-set encounter.
Perez, who is making her singles debut in Paris, recorded a 7-6(5) 3-6 7-5 win against the world No.154.
Arina Rodionova made a promising start in her first-round clash with India's Ankita Raina, but was beaten in three sets.
