A lot depends on your occupation when it comes to Australian immigration.
They have different occupation ceilings for each occupation, there are some occupations which are not even listed under certain visa types. Some popular occupations have only 1,000 spots in a year based on the percentage of people already working in those occupations in the country,, with caveats stating that there are pro-rata arrangements with other visa types. For example, nowadays it's almost impossible to immigrate as an accountant to Australia.
But conversely, if you're in an in-demand occupation, you'll have an easier time of it getting selected, because draws are broken down by occupation as well, with a certain number being invited from each occupation, according to those with the highest scores. But if there is a high ceiling and a relatively low number of applicants for your occupation, your chances are high.
People in trades, nursing, IT and engineering are in high demand in Australia for example.
