When studying in Australia, do you choose a one-year master's degree or a 1.5-year master's degree when it is difficult to immigrate?

In Australia, the standard of master's courses is 1.5 years, and there are few one-year courses. Generally, the master's degree in Britain is one-year. Australia 1.5-year master's program will definitely save time and cost compared with the two-year master's program, and there will be less requirements for guarantee funds including study visas. If you haven't decided whether to take the course of 1, 5 years or 2 years, you can apply for the course of 1.5 years first. If you meet the immigration requirements in the future, you can also apply for a two-year course, or apply for a double degree, which can make up for more than two years of study time. Although Australian immigrants have higher requirements, it is more competitive to accumulate some overseas work experience after studying abroad and then return to China for development. One-year master's program has advantages and disadvantages. Although the academic system is short, it saves time and money. However, because of the short time, I will return to China as soon as I get used to it, and the improvement of my language ability may not be very effective. And it may not be very competitive for future employment.
