I am Australian passport holder, arriving in Hongkong next week and intending to visit Shenzhen for <5 days.

I understand I can apply for visa at HK-China border. However, searching the Web I found conflicting information regarding fees and payment. Some quote HK$ while others mention it has to be paid in Yuan.

Can anyone please tell me the current situation the cost and the currency for a 5 day visa?

Thanks for your attention.
