Australian badminton mixed doubles pair Simon Leung and Gronya Somerville threatened to claim a big scalp before losing their Tokyo Games opener.
The pair won six straight points to pinch the first game 22-20 from fourth-seeded Indonesians Praveen Jordan and Melati Daeva Oktavianti, who had twice toppled the world No.1 team in the lead-up to the Olympics.
The Australians were up 10-5 and 17-16 in the second game too, before being overhauled in a hard-fought 20-22, 21-17, 21-13 victory for the gold medal contenders.
Leung and Somerville must win their next game on Sunday to be a chance of finishing in the top two of their group to progress to the quarter-finals.
Somerville will be in action again on Saturday in the women's doubles with Setyana Mapasa in a group-stage clash.
