Sydney - Australia largest city Sydney has lost its title of world's friendliest in the annual Conde Nast Traveler survey despite the good-natured Australians being so appealing to international visitors.

About 128 000 people who took the survey in 2015 instead chose the US city of Charlestown, thanks to their southern charm, delicious food and unique architecture, broadcaster CNN reported.

Though the beautiful harbour city lost the top ranking it held last year, travellers still can't 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 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.
