Melbourne also has many foreign workers

Like Singapore, Melbourne has numerous foreign workers especially the unskilled ones from China, Pakistan and Middle Eastern countries.
I was in Melbourne not too long ago and was surprised at the number of foreign workers in the city.
The cab driver who took me from the airport to my hotel was a guy from one of the Middle Eastern countries.
During my departure from the hotel a week later, the cab driver was from India. He told me he was on a student visa of some sort. We didn't talk much.

Wherever, I went in the city especially the cafes and restaurants, the waiters and waitresses were either  from China or the countries I mentioned above.
What beats me was that instead of the usual Italians or Greeks migrants serving Italian/Greek food, the Chinese were doing it (I have not been to Melbourne since I stopped flying 12 years ago). You will find Indians selling Chinese food at the eateries or cafes.
Many years ago whenever I visited Melbourne, the Australians were the cab drivers. The restaurants, bars,eateries were manned by the Australians. The Chinese restaurants were owned and run by the Australian Chinese. But it's kind of different now. I am not saying it's a bad thing to have these foreign workers. Perhaps, like Singapore Australia now faces a shortage of these unskilled workers.
