For three years in a row now, Adelaide remained Australia's most liveable city, mainly due to its affordable housing payment schemes, cleanliness and good standard of living, according to a report released by the Property Council of Australia on Monday. Following it on second was Canberra and Hobart at third.

Out of 100 perfect points, residents afforded the city of Adelaide with a liveability score of 63.6 points. Some 600 locals were interviewed and asked to rate 17 attributes of their city, including cleanliness, safety, good healthcare and public transport, among others.

More than 50 per cent of Adelaide residents believe their city offers a good range of quality, affordable housing, while 70 per cent believe Adelaide is clean, well maintained and not polluted.

About 47 per cent of residents agreed Adelaide employs a good approach to environmental sustainability and climate change, thus enabling it to rank second overall across the country under the criterion.

Meanwhile, of the 11 cities ranked, the worst on overall liveability ranking was given to Darwin. Brisbane came in 6th, Melbourne 7th, and Perth 9th.

Although Brisbane was affordable, had a good climate, was clean and unpolluted, respondents felt the city lacked employment and economic opportunities, as well as cultural entertainment scene.

It was the opposite for Melbourne which respondents said possesses a vibrant cultural entertainment scene, an attractive look and design. Its residents also come from a diverse range but fortunately get along well. But Melbourne rated poorly on climate, traffic congestion and safety.

Perth performed well on cleanliness, climate and employment opportunities, but failed on cultural scene, affordability and affordable housing.
