这是准签信里的原话
Do I need a visa label in my passport?
No. Australian authorities do not require you to have a visa label in your passport to travel to,
or enter or remain in Australia.
Are there any situations where I could be asked to show a visa label in my passport?
You will not have a problem entering Australia without a visa label, but rather you may
encounter problems exiting your home country or transiting other countries en route to
Australia.
You should check with the relevant government authorities regarding requirements to show a
visa label in your passport when you transit through or exit a country. The Australian
Government cannot advise on other countries’ requirements.
If the relevant government authorities require you to show a visa label in your passport for
exiting or transit purposes, you will need to check the current process with your nearest DIAC
office. ”也就是说进去澳大利亚他们不需要贴签,但是如果中国处境要求贴签你就必须贴签,为了以防万一,我去贴了,第一天寄过去,第二天就收到护照了,效率很高,上海的。
