What are the advantages and disadvantages of staying in Australia illegally?

Only disadvantages but no advantages

Once caught, you will be sent back to your country and banned from entering the country for life. The only way to stay is to find a local girl to be with. If you live together for two years, you can get PR, which is a green card. Based on your current situation, there are really very few things you can do, such as studying for a TAFE first. People will be exposed as soon as they look at your current visa. . .

PS: 1. There is another way to match the right time and place, that is to apply for political protection, so that you can also get identity. However, you can only apply when there is unrest in China. According to the current political situation This is also unlikely. . .

2. It is really difficult to obtain legal status. With so many international students studying in Australia every year, how many can stay? Many people who have studied here for 5 or 6 years have not been able to stay. The Australian Immigration Bureau is really strict about approval. . .
