Visa Free how does it work going through airport?

Hi all,

I'm from Australia and China now has an agreement for us to travel Visa Free.

Plan on going to Guangzhou.

Just wondering how it works at the airport? Do we line up in the usual lines like we do if we had a Visa? Or we need to go to another line to get a stamp for Visa free?

Reason is one elderly family member still has a valid Visa while the rest of ours have expired so will use the 30 day Visa . Just worried about being separated as the elderly member needs assistance.

Thank you on advanced
