Advance Summary
1. Coalition members of the Joint Standing Committee on Electoral Matters have recently recommended Optional Preferential Voting (OPV), but have provided very little discussion of that recommendation.
2. It is likely the government would have the numbers to pass OPV if both Coalition parties wanted to do so, but unclear as yet if they actually want to proceed.
3. Evidence from NSW state elections under OPV strongly suggests that it would significantly to severely disadvantage Labor if adopted federally. Evidence from Queensland is more confused.
4. The level of likely disadvantage to Labor under OPV could often result in a few federal seats having different results, but could be more severe when Labor holds majority government.
5.Compulsory preferential voting leads to votes being disallowed because of irrelevant errors. Reform to reduce or remove this problem is necessary.
6. Optional Preferential Voting has been defended on the grounds of allowing greater voter freedom, but it can also result in misleading campaigns to discourage preferencing and in cases where parties are disadvantaged because voters make incorrect assumptions.
7. Having OPV as a savings provision rather than a direct instruction to voters would solve most of the problems that OPV addresses with less disadvantages.
8. Labor's arguments against OPV in the report are weak.
