SAO PAULO -- Matildas coach Alen Stajcic doesn't believe in omens.
And he hopes the rest of the Australian Olympic team don't either after his women's footballers opened the nation's Rio campaign with a horror show.
Not only did the first Australians in action at the Rio Games lose 2-0 to Canada.
They also copped the fastest goal in Olympic women's football - 20 seconds.
And conceded another when their goalkeeper was sprawled near the halfway line.
All against a Canadian outfit who played 75 minutes with 10 players after a send off.
Oh, and the result also means their next match against superpowers Germany becomes that much more important.
"It's not the start you want, is it, to an Olympic campaign," a grim-faced Stajcic said after Wednesday's demoralising defeat at Sao Paulo's Arena Corinthians.
The Matildas are removed from the rest of the Australian Olympic team's troubled preparation in Rio which has included a burning building. But they just may have burnt their Olympic bridge - in record time.
In just 20 seconds, the Australians were a goal down.
Laura Alleway sent a sluggish sideways pass towards her defensive counterpart Alanna Kennedy, who didn't sense snooping Canadian captain Christine Sinclair until too late.
Sinclair intercepted, charged at goal, and arrowed a poised pass to teammate Janine Beckie who tapped in the gift from barely one metre out.
The Australians then dominated - 11 shots to two by halftime - but couldn't score.
Stajcic was more perplexed at Australia's lacklustre second half when they failed to press their numerical advantage.
"I don't think the goal in the first minute was the decisive factor," Stajcic said.
"I think our second half performance for 45 minutes was the decisive factor in the result.
"We just lacked the creativity to be able to get in behind them ... we just weren't good enough.
"We weren't clever enough on the ball and lacked the creativity needed to break a defence like that down. I can't remember one chance in the second half, to be honest."
Next up, an encounter against the dual World Cup-winning Germans in Sao Paulo on Saturday from 1800 (0700 AEST Sunday), before a last group game against Zimbabwe three days later.
"You have got to pick yourself up ... we haven't spent one month (training) in Brazil to have a sulk now," Stajcic said.
The top two teams from each of the three, four-team groups qualify for the knockout stages along with the two best-placed sides that finish third.
