When Tim Wilson's $77,000 bill for travelling expenses and taxis was made public last week, the Human Rights Commissioner was quick to defend himself.

"Not indulgent, fly economy, stay in average hotels, all rates are set by an independent body," he wrote in response to one of his Twitter followers who had claimed his spending was "indulgent and unacceptable".

But a detailed breakdown of Mr Wilson's international travel paints a different picture – and it is not one that involves shoestring budgets or "average hotels".
