About 128,000 persons who took the survey in 2015 chose the US city of Charlestown instead, thanks to its southern charm, delicious food and unique architecture, Xinhua news agency reported.
Though the beautiful Australian harbour city lost the top ranking, travellers still cannot get enough, as the good-natured Australians continue to impress visitors.
"Such friendly people, so much so that after we met an Australian woman on our flight there, she offered to pick us up at our hotel and spent a whole day showing us her favourite parts of the city," one traveller said, according to Conde Nast.
"I would live there if possible," another traveller said.
Coming in third was Ireland's Dublin, followed by thrill-seeking destination Queenstown in New Zealand while Park city in the US state of Utah rounded out the top five friendliest cities in the world, according to the survey.
