Australia is a parliamentary monarchy, with a bicameral legislature elected to maximum three-year and six-year terms for the lower and upper house, respectively. In May 2022, Australia held a general election to elect the 47th Parliament of Australia. The next general election (for the 48th Parliament) will occur within the next three years.

From Wikipedia:

The next Australian federal election will be held some time in or before 2025 to elect members of the 48th Parliament of Australia. All 151 seats in the House of Representatives and likely 40 of the 76 seats in the Senate will be contested. It is expected that at this election, the Labor government of Prime Minister Anthony Albanese will be seeking re-election to a second term in office, opposed by the Liberal/National Coalition under Leader of the Opposition Peter Dutton.
