Description

This graphic is a representation of a ballot papers being placed into a ballot boxes.

The Australian Constitution sets a timeframe for when Parliament must meet after a federal election. The Commonwealth Electoral Act 1918 also outlines timing requirements, which help determine when Parliament can open.

The first sitting of a new Parliament must be held within 30 days of the return of the election writs – the documents that formally declare the election results.

Once the timing requirements are clear, the Prime Minister selects a date for Parliament to meet and advises the Governor‑General. The Governor‑General then issues a proclamation – an official announcement – setting the opening date.
