The first time I went to Australia, my visa was granted for half a year. How long will it take for the second application?

Hello, here's the thing The Immigration Bureau stipulates that 600 visa holders cannot stay in Australia for more than 12 months in any 18 months. So if you stay in Australia for six months for the first time and apply for a visa immediately after you come back, you'd better have a good reason first. Secondly, you can only apply for a visa for six months at most this time. If you stay in China for another 6 months before applying for a visa, you can apply for a single visa of 1 year.
