What percentage of Chinese people speak Cantonese in Australia?

I am familiar with the situation in Australia. If all the immigrants, international students and temporary resident visa holders are counted, in fact, 7% of them speak Mandarin, while only about 3% speak Cantonese. Ten years ago, the ratio was indeed about 5%: 5%.

At present, Shanghainese only account for about 1% of the total number of Chinese.

The requirement for finding a job is to be able to speak Cantonese, which is not entirely true. If you work in a restaurant, this sentence is correct. But now some restaurants also accept people who don't know Cantonese. Fortune in Melbourne Chinatown and Emperor Huang now have counter staff who only know Mandarin (and of course English), which was unimaginable in previous years. The reason for this change is that more and more customers speak Mandarin but don't know Cantonese.
