Federal elections come and go every three years, so if you need a refresher on how it all works — and the key 2025 seats to watch — we have you covered.
HOW IT WORKS
To form a majority government, 76 seats are needed for one party.
Polls have sweetened for the Labor party as the election has gone on with most now predicting a Labor government, but whether Labor can win a majority or will rely on crossbench support as a minority government is largely an unknown.
The last time there was a minority government in Australia was in 2010 under Julia Gillard — if a minority government is elected it would be just the third time since 1943.

Cost of living
Labor is offering a “modest” tax cut from mid 2026 as well as promising to implement an instant $1000 tax deduction write off and cutting student debt by 20 per cent. The Coalition has pledged to cut the fuel excise by 25c promising to save the average family $14 a week if they fill up one vehicle once a week. They have also promised to implement a tax offset plan worth up to $1200 for middle-income earners.
Housing
Labor have promised to build 100,000 homes reserved for first time buyers while also expanding their help to buy scheme and increasing access to the 5 per cent home deposit. The Coalition have promised to allow first time home buyers to access up to $50,000 from their superannuation for a home deposit and allow them to claim interest payments on their mortgage as a tax deduction. The party will also spend $5 billion for infrastructure in housing developments to “accelerate” the construction of 500,000 homes.
Health
Both parties have pledged at least $8.5 billion to expand bulk billing services to a goal of 9 in 10 GPs. Both sides will also cut the maximum price of PBS medication by nearly $7 to just $25. The Government has promised to build 50 more Urgent Care Clinics at the cost of $644 million while the Coalition says it will restore the number of subsidised mental health appointments to 20 from the current number of 10.
Energy
The Government has promised to extend its energy bill rebate from July 1 which will see another $150 taken off household’s power bills. It will also spend $2.3 billion to lower the cost of batteries for households by 30 per cent. The Coalition have pledged to build seven nuclear reactors around the country which they say will cost $118 billion although they would not be producing power for at least another decade. Peter Dutton has promised to back the expansion of gas including approving the North West Gas Shelf proposal within his first 30 days in power.
National Security
The Coalition announced it would spend an extra 21 billion on defence before the end of the decade to buy more F-35 fighters and firm the AUKUS deal. The extra spend aims to lift the current share of GDP spent on defence to three per cent in 10 years time compared to Labor’s goal of spending 2.3 per cent of GDP in the 2033-34 financial year. Anthony Albanese did announce a $1.2 billion spend to buy critical minerals for a new strategic stockpile to increase negotiating power.

WHAT HAPPENS WITH THE SENATE?
No party currently has a majority in the Senate with Labor having 24 seats, the Coalition having 30, the Greens 11 and others 10.
A party needs 39 seats to hold an outright majority in the Government, a feat which rarely happens.
Forty seats are up for grabs this election, 18 Senate positions won by Coalition members up for re-elction compared to 13 of Labor’s, six Greens and one One Nation seat as well as David Pocock and Jacqui Lambie.
THE ODDS
Labor are the heavy favourites coming into the election currently having 1.06 odds on SportsBet compared to the Coalition’s 9.50.
The website also has a Labor majority government as the favourite with odds of 1.57 compared to a Labor minority government of 2.88, a Coalition minority government at 10 and a Coalition majority at 34.
The odds are slightly better — but still grim — on TAB with Labor having odds of 1.09 of winning and the Coalition at 7.50.
These are expected to change as the day rolls on.
