Voters over the ditch aren't happy, with the Australian Prime Minister's personal approval ratings taking a plunge.

The latest Fairfax Ipsos poll shows Tony Abbott's approval rating tumbling through November, with 57 percent of voters disapproving of his performance.

Australian correspondent Donna Demaio says politicians don't like to acknowledge polls, but this one's hard to ignore.

She says the opposition leader has leapt ahead as preferred Prime Minister, rated as stronger, more trustworthy, and more competent.
