When Bradbury was elected Mayor of Penrith in his first term, at the age of 24 years, he was the youngest person to hold that office in the city's history.
Bradbury ran for the marginal seat of Lindsay in Sydney's west at the 2001 and 2004 Federal elections, where he was unsuccessful.
Bradbury was re-elected to the seat of Lindsay in the 2010 election in a close electoral contest that he narrowly won by 1,865 votes.
[3] The result in Lindsay played an important role in helping Julia Gillard form minority government in the weeks after the 2010 election.
During his time as Assistant Treasurer, Bradbury was at the forefront of the Labor Government's efforts to crack down on corporate and multinational tax avoidance.
In November 2012 [4], he outlined a number of concerns about base erosion and profit shifting (BEPS) by multinationals, especially the large digital firms.
[2] In this role, Bradbury has been leading a team of economists, lawyers and statisticians who provide country-specific and general tax policy advice, carry out economic analysis, and produce internationally comparable tax data and analysis [5].
At the OECD, Bradbury was a key contributor to the delivery of the OECD/G20 Base Erosion and Profit Shifting (BEPS) Project [6] and its implementation.
