Chinese appetite for property in Australia shows no sign of waning after buyers doubled investment in the nation's homes and offices for a second straight year.

Spending on Australian residential and commercial real estate rose to $24.3 billion in the 12 months ended June 30, up from $12.4 billion a year earlier and $5.9 billion in 2013, according to the Foreign Investment Review Board's annual report.

All Chinese investors in a survey conducted by KPMG and the University of Sydney want to allocate more money to Australia, a separate report showed on Monday.

Real estate is fuelling the capital flowing from the world's second largest economy, which last year overtook the US as Australia's largest foreign investor.
