How long does a search warrant last for in Australia?

A search warrant in Australia generally has a time limit specified on the warrant itself. Typically, a search warrant will have a specific date and time when it is issued, and it will expire after a set period of time, such as 14 days or one month. However, in exceptional circumstances, a court may extend the validity of a search warrant if there are reasonable grounds to believe that further investigation is necessary.

It's important to note that the specific time limits and conditions for search warrants may vary across different states and territories in Australia, and certain circumstances, such as public interest or national security, may affect the duration of a search warrant.
