Australian Consumer Law provides for consumer guarantees, according to which the taking of a particular action (for example, the application of due care and skill) or the presence of a particular fact (for example, a particular quality) is deemed as guaranteed where goods or services are supplied to a consumer in certain circumstances. Remedies lie against the supplier or (where goods are supplied) against the manufacturer or both. Pursuant to its application provisions, Australian Consumer Law applies to conduct outside Australia if one of several alternative criteria is satisfied. One criterion is that the defendant carried on business within Australia. There is no express requirement that the defendant's business activities in Australia include the transaction with the plaintiff. This article argues that comity requires an implied restriction on the territorial scope of the consumer guarantee provisions, and searches for the most appropriate criterion for that purpose.

澳大利亚消费者法规定了消费者保证，根据该规定，采取特定行动（例如，应有的注意和技能的应用）或特定事实的存在（例如，特定质量）被视为有保证的商品或在某些情况下向消费者提供服务。补救措施针对供应商或（在提供货物的情况下）针对制造商或两者。根据其适用条款，如果满足若干替代标准之一，则澳大利亚消费者法适用于澳大利亚境外的行为。一个标准是被告在澳大利亚境内经营业务。没有明确要求被告在澳大利亚的商业活动包括与原告的交易。
