Chloe Rayner (-48kg), Miranda Giambelli (-78kg) and Katharina Haecker (63kg) will all hit the mat for Australia in Rio.
After competing for Italy until 2013, Giambelli donned the green and gold at the Oceania Championships in 2014, and hasn’t looked back.
In the Australian colours, she won her first Oceania Championship in 2015 as well earning silver and bronze at two European Cups.
This year, she won the Oceania title again and secured her place in the top 14 ranking to earn her place.
Giambelli finished in the top 14 of the women’s rankings this year to earn her place.
She will make her Olympic debut in Rio.
Rayner was born in the UK, and moved with her family to Australia at age 9.
After winning five straight senior Oceania Championships, the 19-year-old was struck down by a hamstring injury which sidelined her for four months.
“I missed out on a fair chunk of the qualification period which made it even more difficult for me to qualify for Rio,” she said.
“It has been a dream of mine to make the Games and when I found out I had, it is a feeling I cannot explain.”
Rayner just missed the top 14 rankings to gain automatic selection but secured enough points to fill Australia's extra continental quota.
It will be Rayner’s debut Olympic Games.
“I’m quite young so I am hoping to make the most of the experience in Rio. I definitely want to go there and upset a few fighters and then build on that for my career,” she said.
After winning her third consecutive Oceania Championship title in April 2016, Haecker continued her rise up the rankings into the top 14 and booked her plane ticket to Rio.
Haecker was born in Germany to a German mother and an Australian father giving her a dual passport. She competed in Germany as a junior taking a break to rest for a year in Australia in between two stints of competing in Germany.
She then competed for Australia to win the 2014 Oceania Championship, and at the 2014 Commonwealth Games where she lost the bronze medal bout.
