Over the next week I will publish several posts looking at the abolition of Group Voting Tickets (GVTs) in Victoria and the implications this has for the state’s Legislative Council election in November.
Work I’ve undertaken in the past, about Senate elections both before and after the abolition of GVTs, produces clear conclusions.
Abolishing GVTs will increase the importance of first preference votes and diminish the value of preference transfers. Abolishing GVTs advantages parties that campaign for votes and disadvantages those that rely on deals and transfers to be elected.
Abolishing GVTs also ends the ability of parties to conspire and use GVTs to block the election of high polling parties. It also stops parties using GVTs to elect low-polling parties that few voters have heard of into important upper house balance of power seats.
The key aim of abolishing GVTs is to end party control over between-party preferences and leave it to voters to make the decision. With 95% of votes tied up in party tickets, too many elections had been decided by opaque preferences deals that voters had little knowledge of. A new form of above-the-line (ATL) voting was created allowing voters to show preferences for parties rather than candidates. Voters still had the option to vote below-the-line (BTL) for individual candidates of any party.
In other states this has been implemented with full optional preferential voting. A voter must indicate a first preference for a formal vote, but further preferences were optional. At elections conducted under the new rules, only a third of ATL ballot papers have preferences beyond ‘1’ and exhausted preferences have come to play a part in deciding who wins the final seats. (See my previous post that covered experience with the change in NSW.)
By contrast, the Senate instructions after the abolition of GVTs has been to mark at least six preferences, though a savings provision allows any first preference vote to remain formal. Under these instructions, around 95% of ballot papers are completed above the line (ATL) with between-party preferences. Given the exhaustion rate of preferences for minor party votes, there hasn’t been much difference between the role of preferences in the two ballot marking systems.
Abolishing GVTs makes it nearly impossible to win from a low vote AND from behind on preferences. Abolishing GVTs does not prevent a party winning from a low vote, nor prevent a trailing candidate from winning on preferences, though it does make it harder. But is becomes extremely difficult to do both at the same time.
A party winning from a low vote is possible without GVTs if there is an even split of vote between remaining parties. The United Australia Party’s Ralph Babet won a Victorian Senate seat in 2022 from only 0.28 quotas (4.0%). This was because there were five parties between 0.20 and 0.28 quotas competing for one seat. Without GVTs, preference flows were relatively weak and Babet maintained his lead to win the final seat. Preferences were not responsible for his victory.
And coming from behind is possible. In NSW at the 2025 Federal election, strong preference flows from the Coalition and small right-wing parties allowed One Nation on 0.42 quotas (6.1%) to pass Labor’s third candidate on 0.63 quotas (9.1%).
Without GVTs, the classic 2013 Victorian Senate case of Ricky Muir (Australian Motoring Enthusiasts Party) on 0.5% defeating Helen Kroger (Liberal) on 11.6% would be impossible. Muir’s election was the equivalent of a lower house candidate on 1.7% defeating a candidate with 40%.
As One Nation showed in 2025, is is possible for a candidate with two-thirds of another candidate’s vote to come from behind and win on preference transfers. Voters still have their say on preferences, but without GVTs, results can’t be engineered. Muir’s case of winning from behind with only one-23rd of the winning candidate’s vote is absolutely impossible without GVTs.
And to date, every jurisdiction except except Victoria has understood this inherent problem with GVTs and abolished them. Next week it appears Victoria will be the last to join the club.
Based on One Nation’s two come from behind Senate victories in 2025, I think around 0.4 quotas is the minimum a party needs for victory, 6.5% translated into Victorian Legislative Council numbers. That’s unless you get a case like Ralph Babet’s where a seat remains to be filled and all remaining parties have a low vote.
Looking at how many parties have been elected from trailing positions, the difference produced by the abolition of GVTs for Senate elections is clear.
At the 2013 half-Senate election, the last to use GVTs, 9 of the 36 state Senate positions were won by trailing candidates. At three half-Senate elections since the abolition of GVTs, only 2 of 108 state Senate seats have been won by trailing candidates.
And both of those trailing wins were aided by Senate instructions to mark 6 preferences. Trailing wins may be even harder under instructions for ‘1’ with further preferences optional.
