澳洲的法定声明 Statutory declaration 放到国内可以看作是公证。如果是一些国外的资料，或者是一些直接的英文资料，国内申请人找这类人群也有被认可的。
但需要注意的是，签证申请阶段建议统一用公证，澳洲移民部是根据澳洲法律给出的澳洲境内的 Statutory declarations 资格要求：
A Commonwealth statutory declaration under the Statutory Declarations Act 1959 will need to be witnessed by a person who is both:
- on the list of authorised witnesses (below)
- has a connection to Australia.
For example, a doctor who is registered to practise medicine in Australia can witness your declaration, but a doctor who is not registered in Australia cannot.
Statutory declarations
Only certain people may witness Commonwealth statutory declarations. All departmental offices outside Australia have a person who can witness statutory declarations.
下列人是我们比较熟悉的有资格的 witness：
- 太平绅士 \ Justice of Peace
- 事务律师 \ Solicitor
- 澳洲注册的医生和护士，包括牙医 \ Nurse
- 药剂师 \ Pharmacist
- 警察 \ Police Officer
- 澳大利亚工程师协会会员 \ Member of Engineers Australia
- 税务管理会计师协会会员 \ Member of the Association of Taxation and Management Accountants
- 澳大利亚各会计师协会会员 \ Member of the Institute of Chartered Accountants in Australia
- 教师（全职就职在普通学校或者高等学府） \ Teacher employed on a full-time basis at a school or tertiary education institution
上面说的是澳洲境内认可的有 Statutory declaration 资格的人群。有些概念其他国家没有。对中国大陆来说，一切都可以用公证来代替 Statutory declaration 。
太平绅士（这个中国大陆就没有），这是名义上由政府委任民间人士担任维持社会安宁，防止非法刑罚及处理一些较为简单的法律程序的职衔，但并不是相关的法律界人士，仅仅可以看作一种社会荣誉称号，而且成为太平绅士并不需要任何学历和资格认证的要求，简单来说就是一个社会名号。
太平绅士签阅文案是免费的，是他们的义务也是责任。
事务律师，律师的一种，与讼务律师的区别在于，他们没有资格代表当事人在法庭发表或者代理辩护意见，这类律师通常都在律师事务所里面办公和处理申诉一些法律事件，不过，作为律师的一类，他们所签署的文件和文案效力是能够获得 Statutory declaration 的认可。
实际中，合格 witness 人群一直在变化，下面是 2016 年官方给出的合格人群列表。
