What should Australian families do if they refuse to enter China Customs?

Look at it calmly and ask for help to solve the problem. If you are refused entry, the Australian Immigration Department will give you a letter of explanation and put you in a repatriation center. Usually, the airline will arrange to send you back to China within 3 days. If you feel unfair, you can return to China at the request of the Australian side, and then apply to the Australian Immigration Department for reconsideration or hire a lawyer to sue the Australian Immigration Department. If you are arrested and detained for other reasons, you can hire or ask the Australian side to provide a lawyer, and China citizens also have the right to contact Australian consular officials for assistance.
