Third country to Hong Kong and Macao

You have entered Macau once and Hongkong twice. You have a China passport, which is a bit troublesome.

Both Hong Kong and Macau offer convenience to tourists, and the maximum time for visa-free transit is no more than 7 days.

1) If yes, Australia >; Hong Kong > Macau > Zhejiang, or Australia >; Macau > Hong Kong > Zhejiang, one way, there is no problem

2) If so, Hong Kong > Macau > Hong Kong, so it's not just a transit. Back and forth, China passport is no good.

3) You can go to China Travel Agency and get an endorsement for a trip to Macau, so you can make a stopover to Macau. (the feasibility is 8%, and some of them are impossible. The fees paid are the certificate and the ticket. )
