Australia cruised to a 4-0 win over host nation Vietnam at the AFF U19 Tournament in Ho Chi Minh City.
Young Socceroos coach Paul Okon made nine changes from the side that lost to Uzbekistan and after an uncertain opening half hour the Aussies took control.
Luke O'Dea played in Ryan Edwards who finished smartly on 30 minutes.
The lead was doubled on 53 minutes when Edwards created an opening for Jake Barker-Daish that he converted.
Three minutes later the Young Socceroos increased the advantage with Jesse Makarounas on hand to tap in the loose ball after Reece Caira's shot was blocked by the Vietnam goalkeeper.
Second half substitute Adam Taggart rounded off the scoring on 83 minutes.
"It was a tough first 30 minutes with Vietnam putting us under a lot of pressure trying to stop us playing out from the back," Okon said.
"Credit to our players that they persisted and were able to start to break them down and we got our reward with the first goal.
"In the second half we started very well keeping possession, moved the ball well and as a result we scored three more goals and created numerous opportunities that could have made the score line even greater.
"The final score is pleasing because as in the first game against Uzbekistan we had the same scoring opportunities but we were able to convert them.
"We look forward to the next match against Iran knowing it will be another test as we continue our preparation towards the AFC U-19 Championships in UAE in November."
