A notable trend in Australian politics has been the decline of the share of the vote won by both major parties at federal elections. One effect of this is that there are no longer any safe seats in Australian politics: minor parties and independents win more “safe” seats than they do “marginal” ones.
The declining major party vote
Fewer Australians give their first preference to a major party. The 2007 federal election is the last at which both Labor and the Liberal-National Coalition won more than 40% of the national vote; the 2022 election was the first time that neither cracked 40%.
The share of Australians voting outside of the major parties has increased from single digits in the 1970s to 31% at the most recent election in 2022, almost as many as the 36% who voted for the Coalition and 33% who voted for Labor. Not since the Great Depression has the combined vote for the two largest parties been so low.
The effect of a lower primary vote for major parties is that minor parties and independents have a better chance of winning seats.
