Sydney Airport will welcome a new direct China Eastern Airlines service from Hangzhou, the capital of China's Zhejiang province, from November.
The three-weekly service, to commence on November 16, means Sydney Airport now directly serves 12 mainland Chinese cities.
Sydney Airport managing director and CEO Kerrie Mather said the new service was "fantastic news for the local economy".
The direct flight from Hangzhou was expected to bring 22,000 more Chinese visitors, who will contribute an anticipated $US88 million in additional visitor expenditure per year, she said. The service also links to Beijing, giving passengers travelling to the Chinese capital more options.
Mather described Hangzhou as "one of China's most popular tourist destinations".
"Located on the spectacular West Lake, it's home to many famous historical and cultural sites, making it a unique place to explore," she said.
NSW Minister for Trade, Tourism and Major Events Stuart Ayres said in the year ended June 2016, NSW welcomed 639,000 visitors from China, up 21 per cent on the previous year.
"We are delighted to welcome China Eastern's new Hangzhou to Sydney service which will encourage Chinese travellers to book a trip to Sydney and regional NSW," he said.
"With our iconic attractions, world class arts, cultural and sporting events, award-winning hotels and cultural visitor experiences, we look forward to welcoming more visitors from China as a result of this fantastic new service."
