By contrast, in 1903 there were just 25,000 voters per MP (this being the first election where most women could vote).
In the intervening 122 years, the federal parliament has significantly expanded twice: from 74 to 121 seats in 1949, and from 125 to 148 in 1984. Both times, the number of people per seat sat at a then record high: 64,000 and 75,000 respectively.
Voting rights have also expanded: women’s suffrage came in 1903 (though not for all women), Aboriginal and Torres Strait Islander voting rights took until 1963, and the voting age was lowered from 21 to 18 in 1974.
But while there are nine times as many registered voters today as in 1903, the number of electorates has only doubled.
As the number of voters per MP grows, the access any individual voter will have to their member necessarily decreases – Australia Institute polling research in 2022 found that only 15% of Australians had ever spoken to their local MP (and only 36% knew their name).
And the more voters there are in an electorate, the larger a campaign needs to be to make any difference to the result, giving communities less power to kick out an unrepresentative or under-performing MP.
