Australia's were thrashed by Zimbabwe by seven wickets after being bowled out for their lowest ever total in the ICC U-19 Cricket World Cup on Wednesday.

After winning the toss and electing to bat at the Bogra District Stadium, Australia were skittled for only 73 as Tinashe Panyangara claimed the second-best bowling figures in the tournament's history.

The right-arm quick Panyangara claimed six wickets for 31 runs in a devastating nine-over spell. Four of his victims were caught by wicketkeeper Brendon Taylor.

Elton Chingumbura picked up the remaining four wickets for 17 runs as the Australians were bowled out in 19 overs.

It was a remarkable batting collapse after Australia's openers Tim Paine (19) and Theo Doropoulos (26) had helped the reigning champions to 50 for 1 after 10 overs.

Australia's other eight batsmen managed only seventeen runs between them.

A full house of 15,000 in Bogra saw Zimbabwe wrap up the match before lunch. After losing two wickets in the first three overs, Zimbabwe's batsmen consolidated and lost only one more wicket to win the match in 18 overs.
