Perth is now Australia's most expensive city and the 10th-priciest to live in worldwide, according to an online cost of living index.
Numbeo, a website that claims to collate the world's biggest database of user-contributed data about cities and countries worldwide, now rates the Perth as more expensive than Darwin, Sydney, Canberra and Melbourne for consumer goods, including groceries, restaurants, transportation and utilities.
And the list also christens Perth as the most expensive city in the southern hemisphere, with the rest of the top 10 taken up by cities in Switzerland and Norway - with Trondheim classed as the most expensive place to live in the world.
The Numbeo index, which is updated weekly, is based on a worldwide comparison of prices compared to those in New York City - with Perth rating 121.99, meaning on their analysis the city is 21.99 per cent more expensive than New York.
Almost to prove the point, it was revealed petrol in Perth is set to rise 16 cents per litre on Thursday to a five-year high average of 156.3 cents per litre.
