Mitch Langerak kept a clean sheet in his first UEFA Champions League start for Borussia Dortmund on Tuesday, while James Holland helped Austria Wien to a point away to Zenit St Petersburg.
Langerak began Dortmund's game at home to Marseille in place of the suspended Roman Weidenfeller, who was sent off on matchday one in a 2-1 defeat away to Napoli.
Langerak impressed when he came on at Stadio San Paolo last month, but was unable to prevent the hosts from securing all three points.
The Australian goalkeeper enjoyed a far quieter night this week, with Mathieu Valbuena's on-target free-kick in the first half one of the few times he was called into action, as Jurgen Klopp's team ran out 3-0 winners at Westfalenstadion.
Dortmund are second in Group F, three points behind leaders Arsenal and level on three points with Rafael Benitez's Napoli.
Earlier on Tuesday, James Holland produced an assured performance at the base of Austria Wien's midfield, as they held Zenit to a 0-0 draw in Russia.
Zenit had Belgian Axel Witsel harshly dismissed a minute before half-time, and the remaining 10 men proved unable to break down the stubborn visitors after the break, as Holland and his team-mates secured a first away point in the Champions League for an Austrian club.
Austria Wien, third in Group G, are level on one point with Zenit, and remain highly unlikely to progress ahead of the more-fancied Porto and Atletico Madrid.
The other two Australians at clubs in Champions League action on Tuesday watched on from the bench.
Mark Schwarzer's Chelsea were comfortable 4-0 winners away to Romanian side Steaua Bucharest, while Tom Rogic was also an unused substitute as 10-man Celtic went down 1-0 at home to Barcelona.
Chelsea are second in Group E, three points behind Schalke and level on three points with Basel, while Celtic are bottom of Group H and without a point from their first two matches.
