When Australians go through customs, they can choose to stand in line for either "Nothing to Declare" or "Items to Declare." It works on the honor system, but customs reserves the right to search, and if they find any prohibited or tariffed items being brought in, the passenger has to pay a stiff fine.
原來澳洲入境時，由旅客自己選擇排「免檢查」隊伍，或排「自動申報檢查」隊伍，這雖是一種彼此信賴的榮譽制度，但是海關保留突襲檢查權，一查出不准入境物品，或必須上稅物品，處罰極其嚴重。
