The Sapphires began the clash with Korea well as their starting five controlled the tempo thanks to an early three-pointer from Isabel Palmer (13 points, seven rebounds, four assists) and five offensive boards from Agnes Emma-Nnopu.
Gemma Potter (seven points, six rebounds) then connected from distance as well to give the Sapphires a double-digit lead heading into the first break but Korea locked down defensively in the second term as Australia only extended the margin by a point to half-time.
The Aussies struggled to penetrate through Korea's defences although Palmer notched double-figures herself while Alex Fowler (four points, four boards) matched their opponents intensity with some important minutes off the bench.
Out of the main break, the Sapphires' re-found their touch at the offensive end and a barrage on the scoreboard from the likes of Shyla Heal (12 points, four assists), Potter and Georgia Amoore (12 points, two steals) gave Australia full control.
They doubled Korea's total in the third term and then consolidated that effort with a 25-15 final quarter as every player that hit the court scored once again.
Last-Tear Poa (12 points, eight rebounds, four assists) became the fourth Sapphire in double-figures while Emma-Nnopu finished with eight points and 12 rebounds with her nine offensive boards almost matching Korea's total as a team.
