What is a joint sitting of parliament?

A joint sitting of parliament refers to a meeting where both houses of parliament gather together to discuss or vote on specific issues, legislation, or matters of national importance. This format allows for a combined approach, ensuring that both the House of Representatives and the Senate are represented and can contribute to deliberation and decision-making.

This is often convened in certain circumstances, such as during the passage of legislation that has been blocked by one house or for the purpose of discussing a matter significant enough to require the input of both legislative bodies simultaneously. The concept emphasizes collaboration and unity in the legislative process, distinguishing it from meetings that include only one house or separate meetings of each chamber.

The other options focus on meetings that involve only one chamber or a singular entity, which do not encapsulate the essence of a "joint sitting" where the goal is to bring together representatives from both chambers.
