Commonwealth Electoral Amendment (Ensuring Voter Choice Through Optional Preferential Voting and the Robson Rotation) 2021

# Commonwealth Electoral Amendment Bill 2021: Plain English Breakdown ## What it does This bill would let you vote for fewer candidates than you currently have to in Senate elections. Right now, you must number every single box on your ballot paper in order of preference. Under this change, you'd only need to number your top choice, and could optionally number as many (or as few) additional candidates as you want. The bill also introduces the "Robson Rotation," which randomises the order candidates appear on ballot papers across different voting locations, so the position on the paper doesn't accidentally help or hurt particular candidates. ## Why it matters Currently, many people deliberately vote informal (spoil their ballot) rather than rank all candidates when they don't know enough about them. This change would let people cast valid votes while ranking only the candidates they've actually made a choice about. It could increase the number of valid votes counted and reduce informal voting. ## Key details - **What counts as a valid vote:** Once you've numbered your top choice, you can stop there if you want. But if you number additional candidates, you must do it in order (1, 2, 3...) without gaps. If you skip numbers or repeat a preference, votes after that break get ignored. - **Who's affected:** Senate voters in federal elections. - **When it starts:** The bill doesn't have a fixed start date yet—Parliament will set it within 6 months of the bill passing, or it automatically kicks in after that deadline.
