Australian sisters Caroline and Carmen Marton were able to secure their country berths at the Rio 2016 Olympic taekwondo competition after securing golds at the 2016 Oceania Qualification Tournament.

Caroline was the first of the Martons to star at the event, which took place in Port Moresby, Papua New Guinea.

Returning to the scene of her triumph at the 2015 Pacific Games, the Australian was able to secure gold in the women’s under 53 kilogram event.

Unsurprisingly Carmen Marton, the 2013 women’s lightweight world champion, coasted to victory in the under 67kg competition to all but seal her place at a third consecutive Olympic Games.

She will now set her sights on securing her first Olympic medal, having lost a bronze medal bout at London 2012.

Her husband Safwan Khalil also narrowly missed out on bronze in London, but looks assured of a place at his second straight Games after winning the men’s under 58kg competition.

A fourth gold and Olympic quota place for Australia was secured in the men’s under 80kg division, with Shkara Hayder finishing on top of the podium.

Home success also proved to be a family affair, with Samantha Kassman earning a berth for Papua New Guinea in the women’s under 67kg competition.

Samantha had claimed a silver medal at the Pacific Games in front of a home crowd, but now looks likely to head to Rio 2016.

Her nephew Maxemillion Kassman ensured the country would be represented by two taekwondo players at the Games for the first time by winning his under 68kg men’s division.

The final two gold medals were claimed by New Zealand’s Andrea Kilday in the under 49kg event and Tonga’s Pita Taufatofua in the men’s over 80kg competition.

Taufatofua's triumph ensured that Tonga would be represented for the first time at the Olympics in taekwondo.

National selectors will have to confirm their athletes' places at the Games, with the final decisions due to be revealed on the World Taekwondo Federation’s website on July 18.
