The Australian top seed was too strong for second-seeded compatriot Louisa Ma in the final at Ken Kay Badminton Stadium, winning 21-17, 21-15.

She saw off another Australian, Sylvina Kurniawan, 21-11, 21-5 in the semi-finals which were also held today.

Ma defeated fourth-seeded team-mate Tiffany Ho 21-17, 21-19 in her last-four clash.

No player has won six titles in a row in any of the Oceania Championships events before.

"It was a lot of pressure and I tried to overcome that," said Chen. 

"It feels great to win my sixth title."

New Zealand's top seed Abhinav Manota won the men's singles title and later added doubles gold.

In the singles final he beat unseeded compatriot Edward Lau, the reigning Oceania junior champion, 21-17, 21-15.

This followed a 21-16, 21-8 win over Australia's Nathan Tang in the last four.

Lau dispatched Milain Lohith Ranasinghe of Australia 19-21, 21-14, 21-18 to reach the final.

"I am very happy to win the title this year as it will contribute to the Olympic qualification," said Manota, who regained the crown he won in 2018. 

"I came to Ballarat with a plan and I am glad it worked."

In the men's doubles final Manota teamed with Oliver Leydon-Davis to beat Australia's four-time champions Matthew Chau and Sawan Serasinghe 18-21, 21-9, 21-14.

Gronya Somerville of Australia was able to celebrate gold in both the women's and mixed doubles finals.

She joined Setyana Mapasa to beat New Zealand's Sally Fu and Alyssa Tagle in the women's doubles final, 21-9, 21-10.

In the mixed she partnered Simon Wing Hang Leung as they saw off compatriots Tran Hoang Pham and Kurniawan 21-12, 21-8. 

The Championships will now continue tomorrow with the start of the team event.
