Bernard Tomic and Thanasi Kokkinakis are safely through to the second round of French Open qualifying in Paris.
After a dismal 2017 and fleeting appearance on reality TV, Tomic continued his resurgence with a 7-6 (7-4) 6-0 victory over Darian King of Barbados.
The win was Tomic's fifth from his past six matches on clay and left the former Wimbledon quarter-finalist two victories away from a place in the Roland Garros main draw.
Kokkinakis battled back to beat the 206cm French teenager Jaimee Floyd Angele 1-6 6-3 6-1 in the Australian's first competitive outing since injuring his knee in an on-court fall at last month's Madrid Masters.
Countryman Akira Santillan also won his first-round qualifier, brushing aside Japan's Go Soeda 6-2 6-2, but Marc Polmans, Alex Bolt and Jason Kubler all bowed out.
Polmans succumbed 5-7 7-6 (7-4) 6-2) to Belarusian Uladzimir Ignatik, Bolt lost 6-2 6-4 to German Tobias Kamke and Kubler went down 6-2 7-5 to Portugal's Goncalo Oliveira.
Tomic and Kokkinakis will continue their bids to join Nick Kyrgios, John Millman, Matt Ebden, Jordan Thompson and 19-year-old wildcard Alex de Minaur in the 128-man Open main draw on Wednesday night.
Australians Olivia Rogowska, Arina Rodionova, Lizette Cabrera and Priscilla Hon all play their women's first-round qualifying matches on Tuesday night.
Seeded stars Ashleigh Barty and Daria Gavrilova and former Roland Garros finalist Samantha Stosur all continued their Open build-ups with first-round wins in Strasbourg overnight.
Barty lived up to her top seeding with a 6-4 6-4 victory over Thai qualifier Luksika Kumkhum, while second-seeded Gavrilova set up a rematch of her all-Australian final last year with Stosur with a hard-fought 7-6 (10-8) 7-6 (8-6) win over American Jennifer Brady.
Stosur fired down 12 aces in a 6-3 6-2 rout of American Sofia Kenin in an impressive start to her title defence.
