Ashleigh Barty expressed joy and relief after finally breaking her Wimbledon duck to lead an Australian stampede on day two of the championships.
Barty's 7-5 6-3 success against Swiss Stefanie Voegele ended the former junior champion's seven-year wait for a main-draw win at The All England Club.
"Regardless of whether it's a first round or a final, I'm out there to try and win a match and it was certainly nice to give myself a chance in the second round here at Wimbledon," said the 17th seed.
"I love these courts so it's nice to get my teeth stuck into the tournament a little bit."
Victories also for Daria Gavrilova, Samantha Stosur, men's spearhead NIck Kyrgios, fellow former quarter-finalist Bernard Tomic and seed slayers Matt Ebden and Alex de Minaur on Tuesday, plus John Millman's on day one, have given Australia its best start to the grass-court grand slam in three years.
Barty battled back from 5-3 down in the opening set to reel off eight straight games and seize command against her 93rd-ranked opponent, a player she took care off in straight sets en route to the title in Nottingham two weeks ago.
"Really tricky conditions. Obviously first rounds are always tough as well and Stefi came out with a bit of a different game plan to what she did a few weeks ago," Barty said.
"So it took me a while to adjust and it certainly wasn't my best tennis, but I did enough to get through and that's all we need."
Barty will play fellow former Wimbledon junior girls' champion - and 2015 women's runner-up - Eugenie Bouchard next after the Canadian continued her run from qualifying with a win over British wildcard Gabriella Taylor.
Gavrilova dismissed American teenager Caroline Dolehide 6-2 6-3 to set up an all-Australian showdown on Thursday with Stosur, a 6-4 7-5 victor over China's Peng Shuai.
"That's an opportunity for both of them, a guaranteed Aussie in the third round and hopefully I can join one of them," Barty said.
Kyrgios and Tomic could also square off after opening their campaigns in contrasting fashion.
Kyrgios could only manage one service break against Denis Istomin, relying on 42 aces to see off the Uzbeki 7-6 (7-3) 7-6 (7-4) 6-7 (5-7) 6-3 and progress to a meeting with Dutchman Robin Haase.
"Very tough match. I didn't play anywhere near my best tennis today," said the 15th seed.
Tomic took full advantage of his lucky loser lifeline into the main draw with a routine 6-4 6-2 7-6 (7-2) win over Polish world No.122 Hubert Hurkacz.
A former quarter-finalist like Kyrgios, Tomic will play Japanese star Kei Nishikori for a likely shot at his one-time Davis Cup teammate.
Ebden claimed the biggest grand slam scalp of his career, 10th seed David Goffin, with a 6-4 6-3 6-4 triumph over the Belgian who scuppered Australia's Davis Cup hopes last year in Brussels.
On debut, teenage ace de Minaur completed Australia's memorable day with a spirited 6-4 6-7 (6-8) 7-6 (7-5) 6-4 triumph over French Open semi-finalist and 29th seed Marco Cecchinato.
But James Duckworth lost 7-5 6-2 6-0 to German world No.3 Alexander Zverev and qualifier Alex Bolt went down 6-2 6-3 7-5 to British hope Kyle Edmund, the 23rd seed.
