Malcolm Turnbull's wife, Lucy Turnbull, has been appointed an Officer (AO) in the Order of Australia.
It's been an eventful year for the Turnbulls. Millionaire Liberal MP Malcolm Turnbull reversed his decision to quit federal politics, daughter Daisy was married in December, and now his wife, Lucy Turnbull, has been appointed an Officer (AO) in the Order of Australia.
"It's been a big year," Ms Turnbull, 52, told AAP.
"I'm very excited and very honoured."
Her husband was very happy for her, she added.
Ms Turnbull has been recognised on Australia Day for her distinguished service to the community, including her support and fundraising for medical, social welfare, educational and cultural organisations, as well as for her contribution to local government and business.
The former Sydney Lord Mayor is involved in several charities and boards, but says cancer research is one of the areas she is most passionate about. "If I hadn't been a lawyer, I would have loved to have been a scientist," she said.
Ms Turnbull is currently chairman of Biomed, a cancer treatment company that is developing a treatment for ovarian cancer. "It's exciting because it taps into my deep level of interest in cancer treatment and care, but also Australian innovation," she said.
The Sydney-based Turnbulls founded The Turnbull Foundation charity in 2001 and Ms Turnbull is also involved with the NSW Cancer Institute, the Wayside Chapel and the Salvation Army. She is a board member of the Biennale of Sydney and was recently appointed deputy chair of a panel set up to look at Australian capital city planning.
"City planning is another passion of mine," she said. Ms Turnbull also works with the Redfern Foundation, which supports Aboriginal-run businesses in inner Sydney and she is director of Turnbull and Partners, a private investment bank.
Asked how she finds the time to fit everything in, Ms Turnbull laughed.
"It goes in peaks and troughs, thank goodness," she said.
