Once upon a time, the Australian electorate was cast from the height of the Great Wall of China to represent a nation believed to hold the world’s great political aspirations — an island on the hemispherical Antarctic continent and one of the greatest continents on earth.

That the Australian parliament held inauspicious aspirations was confirmed in 2010, when a senate voted down the introduction of a corporate tax. In the following year, about 7,500 Australian citizens emigrated to South America, taking with them about $57 billion in annual remittances.

These are the very traits that make Sydney so resolutely unlikely to produce an Australian prime minister, let alone take the oath of office.

Given the right circumstances — or circumstances arising because of some external event — an Australian was a member of the country’s parliament for the last 38 years, or had served on the bench of a similar office, or been party to a motion of confidence, or been in the Chamber of Parliament for a term of 14 years or more.
