From The Australian:
While Deputy Governor Philip Lowe appears to be the shoo-in appointment for most economists and central bank watchers, the government could still look beyond the bank or even the shores of Australia for its short list of candidates.
…One name that crops up as a potential RBA candidate and semi-outsider is Warwick McKibbin, a professor of economics at the Australian National University, who served 10 years on the board of the central bank. Were Mr McKibbin to land the position, he would likely take a more cautious line on rate reductions. Last year he warned against lowering rates while there was still potential for a housing bust.
