I am the first member of an Australian parliament from a classical liberal or libertarian party.
I've held an interest in politics since the early 1970s when, as a member of Young Labor, I worked on the It’s Time campaign to help end military conscription.
In an effort to promote economic freedom I later joined the Liberal Party - resigning in 1996 due to John Howard’s extremist gun laws.
I joined the Shooters Party and as Chairman, managed the successful 2003 campaign that retained the party’s NSW Legislative Council seat.
I joined the Liberal Democrats in 2005 when it had fewer than 200 members. I was elected to the Senate in 2013, re-elected in 2016, and the party now has around 6,500 members.
I have been married for 33 years and own an agribusiness company in Sydney. I am a former veterinarian and also have degrees in business and law. My main sporting interest is target shooting and my favourite music is opera and classic rock.
