Overall, the figure for the entire continent stood at 8,000 as Melbourne and Perth attracted 3,000 and 1,000 high net worth individuals (HNIs) and secured second and eighth positions, respectively, according to a report by New World Wealth.
"Sydney, Melbourne and Perth all benefited from millionaire inflows from China, Europe, the UK, the US and South Africa. Other Australian areas such as the Gold Coast, Brisbane, Noosa and the Sunshine Coast also experienced inflows," the report said.
Other Israeli cities such as Herzliya, Jerusalem and Netanya too saw inflows.
There were large millionaire inflows to San Francisco, Seattle and Vancouver from China and South East Asia while Dubai pulled in many from North Africa (Egypt, Algeria and Morocco) and Turkey.

Interestingly, in 2015, London saw an inflow of 3,000 millionaires, but 2,500 super-rich left the city and moved to other parts of England. A large number also moved overseas, mainly to English-speaking countries such as Australia, Canada, New Zealand and the US.
Paris saw the biggest outflow, with as many as 7,000 of millionaires heading the exit door. The other cities with large outflows of millionaires include Rome (5,000), Chicago (3,000) and Athens (2,000).
The factors responsible for millionaire migration varied widely. For Paris, it was rising religious tension and lack of opportunities; for Rome, economic slump; for Chicago, rising racial tension and rising crime levels, and for Athens, economic slump and migration crisis with Syria/Turkey.
