Chinese real estate developers are increasing investment in the overseas market as a growing number of Asian investors have become keen on buying foreign properties, according to an industrial survey.

According to the study by Colliers International, a property service provider, up to 73 percent of Asian buyers will increase overseas investment in 2015, sending a positive signal of confidence in the Asian property market in the near future.

"As a result, Chinese developers have increased investment in key destinations, such as Sydney," said Lin Guodong, general manager of Colliers International (South China).

For example, Greenland Group, one of the Fortune Global 500 enterprises, has developed a luxury residential project in Sydney, which is situated in the heart of the western part of the city.

According to the survey, up to 26 percent of Asian investors will buy properties in Australia.
