Melbourne named world's most livable city again, Adelaide ranked fifth

It is the fifth time Melbourne has been named Australia's most livable city.

Melbourne has been named the world's most livable city for the fifth year in a row, achieving a near perfect score on the Economist Intelligence Unit's (EIU) livability survey of 140 cities.

The survey rated cities out of 100 in the areas of health care, education, stability, culture and environment and infrastructure.

Melbourne again achieved a score of 97.5, just two-and-a-half points shy of perfection.

The five most livable cities:
  1. Melbourne, Australia
  2. Vienna, Austria
  3. Vancouver, Canada
  4. Toronto, Canada
  5. Adelaide, Australia
"Those that score best tend to be mid-sized cities in wealthier countries with a relatively low population density," the EIU report said.

"These can foster a range of recreational activities without leading to high crime levels or overburdened infrastructure."

Seven of the top 10 scoring cities were in Australia and Canada.

The report said civil unrest and acts of terror had triggered stability declines around the world including in France and Tunisia.

The "ongoing actions" of Islamic State had created a further heightened threat of terrorism in many countries.

The Syrian capital Damascus saw the biggest fall in liveability scores over a five-year period.

Zimbabwe's capital Harare was the most improved city in the EIU report.

"No place like Victoria"

Melbourne is Australia's fastest-growing capital and the only city in the world to have won the title five consecutive times.

International visits have increased by 8 per cent in that time.

While celebrating the ranking, the Victorian Government said it would "never be complacent", investing $20 billion in transport infrastructure and $5.4 billion in health and education to create a stronger economy.

"Melbourne has the best of everything and this title proves it," Victorian Premier Daniel Andrews said.

"Perfect scores in health care, education and infrastructure, culture, environment and sport are all proof there's no place like Victoria."

Melbourne Mayor Robert Doyle said he was "very proud" of the accolade.

"It is particularly pleasing in a year when the Economist Intelligence Unit notes that many cities lost ground," he said.

"We must be doing something right in our cities in this part of the world."

The five least livable cities:

  1. Tripoli, Libya
  2. Lagos, Nigeria
  3. Port Moresby, PNG
  4. Dhaka, Bangladesh
  5. Damascus, Syria
