In Australia, there is no minimum number of signatures required for a petition to be presented to the House of Representatives. A petition can be presented with as few as one signature. However, if a petition has 50 or more signatures, the Petitions Committee may refer it to a minister for a response. For larger petitions, such as those with over 10,000 signatures, different parliamentary committees may become involved depending on the legislative body. For example, in New South Wales, petitions with 500 or more signatures need certification by a Member of the Legislative Assembly, and those with over 10,000 signatures get special announcements in the House. Generally, the process can vary slightly between different states and territories, but the minimum signature requirement is commonly just one signature to present a petition officially in Australia.
