Patrice O'Neill has led the Australian women's water polo team to a 19-3 thrashing of Japan to close out FINA World League qualifying series.
O'Neill top-scored with four goals and Mia Santoromito netted three to secure the Stingers' sixth-straight win for the tournament.
The Stingers have also qualified for the Super Finals in Tenerife, Spain on June 10-15.
The Australians were dominant in the pool, keeping Japan scoreless until the final minutes in the last quarter before a slip in concentration allowed three quick goals to Japan.
The team returns home for a short break before flying to Spain for the Super Finals, after which the team for the Olympic Games in Beijing will be announced.
