In Australia, privacy and loyalty titles (also known as confidentiality or confidentiality documents) are often used in Australia. These documents are generally used for the same purpose and contain provisions similar to other local provisions that are akin to undisclosed agreements (NOAs). However, these documents are treated legally as deeds and are therefore binding without consideration, unlike contracts. In the NDA`s standard agreement, the « revealing party » is the person who reveals secrets and the « receiving party » is the person or company that receives the confidential information and is required to keep it secret. The conditions are activated to indicate that they are defined in the agreement. The model agreement is a « unite » agreement (or in a legal agreement, « unilateral »), that is, only one party reveals secrets. A Confidentiality Agreement (NDA), also known as a Confidentiality Agreement (CA), Confidential Disclosure Agreement (CDA), Intellectual Property Information Agreement (PIA) or Confidentiality Agreement (SA), is a legal contract or part of a contract between at least two parties that describes confidential information, knowledge or information that the parties wish to share with each other for specific purposes. , but which limit access. Physician-patient confidentiality (doctor-patient privilege-privilege), solicitor-client privilege, priestly privilege, bank client confidentiality and kickback agreements are examples of NDAs that are often not enshrined in a written contract between the parties. A confidentiality agreement can protect any type of information that is not known to all. However, confidentiality agreements may also contain clauses protecting the person receiving the information, so that if they legally receive the information through other sources, they would not be required to keep that information secret.
 In other words, the confidentiality agreement generally requires that the receiving party process confidential information only if that information has been transmitted directly by the publishing party. However, it is sometimes easier to get a recipient party to sign a simple agreement, which is shorter, less complex and does not contain security rules to protect the recipient.
