Sailing from the age she could walk on her home waters in Pittwater, Nina competed in her first international Match Racing Regatta at the age of 15. She then went on to win five National Championships and numerous International regattas. Between 2009 and 2012, she won multiple World Cup Series events and Women's Match Racing World Championship Gold in 2009, Silver in 2007 and Bronze in 2010.
This impressive performance led to her selection for the 2012 London Games, where she claimed a silver medal alongside her teammates Olivia Price and Lucinda Whitty. The same year she was awarded Australian Sailor of the Year.
Following the 2012 games, Nina set her sights for Rio 2016 in the Nacra 17 with Darren Bundock and 49er FX with Haylee Outteridge campaigning in both classes. Over the next five years, she medalled at 12 ISAF World Cup events and, unfortunately, narrowly missed out on Olympic selection in both classes in 2016.
Nina joined Team Brunel in the Volvo Ocean Race 2017/18 in Aukland ahead of the renowned Southern Ocean leg. Nina won her debut leg with Team Brunel also leading the fleet around Cape Horn. There on, it seemed that Team Brunel were on a charge; winning 3 legs and arriving 2nd in another. A final leg through the North Sea, that would see the fleet briefly visiting Aarhus, decided the overall winners of this edition of the Volvo Ocean Race. Although tied for first place until the final hours, Team Brunel finished an impressive third place into their home port.
Nina joined team Moneypenny on the bow for the 2020 Rolex Sydney Hobart competing in all the lead up events which unfortunately due to COVID-19 was cancelled. She remains on the team to the this day. Most recently winning the Sydney to Gold Coast Race 2022.
Nina continues to move from strength to strength becoming the first female sailor to ever win the SailGP Championship in Season 2. She rejoins SailGP Team Australia in their bid to get 3 back-to-back championship wins.
Outside of sailing Nina continues her work in the fitness industry by coaching, holding seminars and mentoring young athletes.
