Travel to Australia before residence permit

Hi,

I have a visa Z which is 1 entry but I need to go to Australia for business 12 days after my arrival in Shanghai.

The agent in charge of my case told me it will be too short in time for me to have the residence permit but I will have a paper notifying the application was made and that my physical check was done.

Can I go to Australia and re-enter China if I apply for a L visa in Australia even though my residence permit isn't issued?

I've seen above something about a "temporary residence permit" how can you get this?

Thank you very much
