Dear Sir

I am an Australian citizen travelling on an Australian passport. I will be flying China Southern airlines into Guangzhou from Cambodia and have a 21 hour stopover in Guangzhou before continuing on to Sydney.

I would like to leave the airport during this period.

Can you answer the following questions for me
-- do I need a transit visa
-- can I obtain the Visa at the airport on entry to Guangzhou -- (note my arrival is approximately 22:00 hours), or do I need to obtain it before I enter Guangzhou
-- do you know the cost of the Visa

I am very grateful to you for your advice.

Greg
