Australia have won their opening two games of the FIBA 3x3 Under-18 World Cup, defeating ninth ranked Switzerland before knocking off the number one seeded Hungary on their first day of competition.

In the fast-paced style of 3x3, games are played for ten minutes or until the first team hits 21 with regular two-pointers counting for just one and shots from beyond the arc counting for two.

Australia v Switzerland

In the opening game against Switzerland, Lana Hollingsworth, Rashada Kaigey and Ula Motuga started with Alexandra Fowler coming off the bench.

With an evident height advantage, Australia utilised Motuga early whose drives and work in sealing a position under the rim helped her team to a 4-2 early lead.

Hollingsworth (two points) showed her ability to defend the perimeter with a big swat to force Switzerland into a shot clock violation and then Motuga (seven points) drew contact on a lay-up for an and-one play to give Australia some breathing room.

Out of a time-out, Switzerland found their outside game to quickly tie the game at 6-6 but even when Motuga missed, Fowler (three points) was there to clean up the glass for the Aussies and give them the response.

Switzerland tightened up their defence just when it looked like the game was getting away from them and Dahlia Miranda Monteiro knocked down a couple of two-point daggers to once again tie the game with 1:30 remaining.

Fowler responded with another seal under the rim and the 15-year old connected on the clutch and-one play to give the Aussies an edge.

Miranda Monteiro got free for another two-pointer with 40 seconds left but Kaigey (two points) came alive with an incredible no-look lay-up through contact.

Her free-throw was pure as well to give Australia a 14-13 lead inside the last 30 seconds.

The Aussies' defence forced Switzerland into a shot clock violation on the following possession and while the Swiss had one last chance to send it into overtime, the Aussies' defence impressed once again to claim victory in their opening game.

Australia v Hungary

Coming into their second game of the night for both teams, the number one seeded Hungary were looking to avenge a loss to the USA but the tight defence from starters Fowler, Motuga and Hollingsworth made things difficult.

They began the game by forcing a shot clock violation and through help defence and some strong one-on-one play under the rim, the Aussies continually blocked Hungary's shot attempts.

Kaigey then came off the bench and forced her way down the lane before a Hollingsworth rejection set her up for another drive which she completed on a fantastic hesitation move.

That determination to get to the rim gave Australia a lead but Hungary were able to answer with a couple of pull-ups and shots early in the shot clock.

Hollingsworth (four points) calmed the tempo from the free-throw to put the Aussies back ahead 8-7 halfway through the contest before Fowler (one point) became the third Australian to record a block.

Hungary re-took the lead on a two-pointer as the game entered the final three minutes but they had no answer for Motuga who then put together a scintillating minute of play.

She first pulled down the defensive board and retreated hastily to the arc where she drilled a two-pointer and on the next offensive possession, she drove to the hoop for a tough lay-up, pushing Australia's lead to 13-10 in a blink of an eye.

The Hungarians hustled on the following possession as the game entered the final minute, grabbing a series of offensive rebounds before connecting on an and-one shot to trim the margin to one.

Motuga (six points) was too strong down low though, answering immediately with a simple basket and that forced Hungary to foul with Kaigey (four points) pushing the margin out to three as the clock wound down, resulting in a stirring 15-12 victory.
