"The significant increase puts Australia in the first place among the top ten sources of Bali`s foreign tourists," I Gede Suarsa, the head of the Bali Central Bureau of Statistics, said here on Tuesday.
Most of them came through Ngurah Rai airport by plane straight from their country, and only 7,135 came by ships or yachts.
In 2010 the number of Australians holidaying in Bali reached 641,588, a 43.67 percent increase compared to 2009 when the figure -was 446,570.
Australians have become increasingly interested in Bali, as they consider the paradise island their "second home". Besides, Bali is just a short flight away from Australia while the Australian economy is improving.
