[5][6][7] Creighton holds a Bachelor of Economics with First Class Honours from the University of New South Wales, and Master of Philosophy in Economics from Balliol College, Oxford, where he was a Commonwealth Scholar, and was a journalist-in-residence at the University of Chicago Booth School of Business in 2019.
[9] Creighton has previously worked at the Reserve Bank of Australia, Centre for Independent Studies and the Australian Prudential Regulation Authority.
[9] Creighton is regarded as holding generally conservative views and has been described by Jason Wilson of The Guardian as an "arch-neoliberal",[10] though Creighton contests that definition and describes his views as "old DLP Labor sprinkled with a bit of libertarianism"[11] and points to his stance in favour of land and inheritance taxes, a higher top marginal tax rate for very high incomes, tougher bank and pharmaceutical regulation, abolishing negative gearing and a universal age pension, and his advocacy against privatisation of energy markets.
[22] Creighton has referred to strict lockdowns as an affront to personal liberty and reflective of what he calls "health fascism".
[23] In April 2020, Creighton signed a joint letter with several dozen people from academia, business and media, calling for a scaling-back of Australia's lockdowns by May.
