Ho Chi Minh City: Australia coach Jeff Hopkins knows his side is in for another difficult encounter when they take on DPR Korea at Thanh Long Sports Centre but believes they have enough firepower at their disposal to collect a second consecutive victory at the AFC U-19 Women's Championship.

Australia began their campaign in winning fashion against Vietnam but had to dig deep to overcome the hosts. Trailing 3-1 with an hour gone, they were thankful for Emily Gielnik's hat-trick that saw them run out eventual 4-3 winners.

Hopkins felt the game will prove a wake-up call for his players as to the standards they need to reach if they are to take the trophy back home and he is under no illusions that a clash with DPR Korea, who saw off neighbours Korea Republic 2-1, will prove to be any easier.

However, he has confidence Australia can rise to the challenge despite having just a day to recover from their tribulations against the Vietnamese.

"We've seen a little bit of their Under-17s from the last World Cup but we know that sides that come out of DPR Korea are going to be very, very difficult to beat," said Hopkins.

"They'll be together, well organised, good technical players, physically fit as well and with their system, they might cause us a few problems that we're not used to.

"We've got a little bit of an idea about them, we're going to have a look at them before the game, but we'll back ourselves."

Although everyone completed the game with Vietnam relatively unscathed, Hopkins was far from satisfied with the performance his side produced and as such, promised to ring the changes against the Koreans.

"We came through the game reasonably well injury-wise, one or two suffered with the heat," he added.

"I wasn't overly pleased with the performance so there will definitely be a few changes to the team."

DPR Korea also had to come from behind against their southern neighbours to join Australia at the top of the table on three points, Kim Su-gyong netting the winner with nine minutes to go.

Boss Sin Ui-gun confessed he has no prior knowledge about their opponents but promised they would be looking to cement top spot with another win.

"We don't have any information on Australia so I can't say anything now but generally speaking, they are a good team," he said.

"We are definitely aiming at gaining another three points against Australia."
