New Zealand isn't the only country fretting about property prices.
Across the Tasman, the Australian government launched a parliamentary inquiry into home ownership in May, hoping to get to the bottom of its alleged housing affordability problem.
Or as the inquiry chair, Sydney-based Liberal MP, John Alexander, said via press release: "The committee wishes to examine whether the current policy settings are optimal to ensure that all Australians have a chance to own their own home."
On the balance of the evidence so far, it seems no one is particularly happy with the policy settings: there is little optimism about the optimality.
