Can official website, the Australian Immigration Bureau, find out the specific information of visa refusal?

As long as you submit the visa, official website and Australian Immigration Bureau can find the relevant information, but generally, after the visa is refused, the embassy will send you a refusal letter with the general reasons for refusal, which is actually of little reference significance.

Only the embassy knows the real reason for the visa refusal, and you don't have the channel for this reason, because this is the internal system of the embassy. Only people inside the embassy can know that the tourist visa has been refused, and it is normal to be afraid that you will not come back after you go.

In fact, it has nothing to do with the time when the Australian visa was refused. The key is whether your binding force is stronger than last time. If the binding force is more than last time, you can sign it again at any time.

If you don't change anything, that is, the binding force remains the same as last time, even if you sign in 10, the result will still be rejected.
