Australia plans to impose a new tax on foreign property buyers after Chinese investment in Australian real estate soared 60 percent last year, in the latest sign of a gathering international backlash against wealthy Chinese property investors.

The move, which came after locals complained about being priced out of the housing market, follows the introduction of similar, more punitive, taxes in Hong Kong and Singapore aimed primarily at discouraging the flood of mainland Chinese money into those markets. Governments in all three locations say that the new taxes are not directed at any single nationality. In the past year, mainland Chinese buyers have become the biggest single group of foreign investors in residential property in the US, UK and Australia, as well as in key cities in other western countries, according to real estate brokers. In the year to March 2014, mainland Chinese buyers accounted for nearly a quarter of all foreign purchasers of residential real estate in the US, spending about $22 billion, compared with $12.8 billion a year earlier, according to the US National Association of Realtors. Canadians, the second biggest group, spent $13.8bn in the same period. Most apartments being built by Chinese developers in prime markets such as New York, London and Sydney are also being sold directly to mainland Chinese buyers.

The UK, Australia, Canada and the US are the most popular destinations for Chinese real estate investment. Australia had the strongest growth in inbound real estate investment from China in 2014, with an increase of more than 60 percent, according to estimates from property consultancy Knight Frank, based on official Australian data. In London, Chinese buyers accounted for 11 percent of all property transactions above £1 million in 2014, up from 4 percent in 2012, according to Knight Frank. The comparable figure for Russian buyers, the second-largest group, was 5 percent — a proportion that has hardly changed for several years. Total value of investment in overseas real estate by Chinese institutional investors has also ballooned from $600 million in 2009 to about $15 billion last year, according to Knight Frank estimates.

"But . . . we have seen estimates from the US, Australia and UK showing 20-30 percent of foreign buyers are from China." Analysts say the rush of Chinese money into western property markets is the result of a complex combination of factors. The enormous overcapacity and recent slowdown in China's domestic property market has pushed many wealthy people to diversify their investments into offshore assets. This has been made easier and more attractive by the collapse in property prices in many western markets that followed the 2008 financial crisis and the huge rise in Chinese prices over the past decade.
