There were four winners and two losers as Australia's hopefuls began Wimbledon qualifying on a sweltering day in Roehampton, southwest London.
Dane Sweeny, Tristan Schoolkate, Chris O'Connell and Bernard Tomic were the victors, the first three of those living up to being seeded 11, 28 and 32 respectively.
However, James McCabe and Alex Bolt are out.
Tomic now plays O'Connell with the winner one match away from a place in the main draw.
Tomic, a Wimbledon quarter-finalist 15 years ago aged 18, defeated Japan's Kaichi Uchida 6-3 6-2. O'Connell, fresh from winning his first grass-court event, the Nottingham Open, on Saturday, beat Joel Schwaerzler of Austria 7-6 (7-3) 6-4.
Schoolkate defeated local wildcard Johannus Monday 7-5 6-3 and will next meet another Briton, Dan Evans. The 36-year-old former world No.21 is trying to reach his final Wimbledon the hard way after criticising the organisers' decision not to hand him a wildcard. He has announced he will retire after the championships.
