The Australian Parliament provides a formal process for creating an official House of Representatives e‑petition. Any Australian citizen can lodge a petition request if it meets parliamentary guidelines. This includes proposals such as a petition relating to a federal pardon for Ben Roberts‑Smith, provided the topic is permitted under the rules.

Information and the petition request form are available here:

The official page outlines how petition requests are submitted, vetted, approved, and how signatures are collected once authorised. Discussion about whether an e‑petition should be drafted can continue in the comments.
