Australian party leaders catch breath as campaign bus reaches final stop

Anthony Albanese and Peter Dutton have paused for the day before the two leaders attend political events in the evening.

As polling booths in the eastern states prepare to close at 6pm, both leaders finished up on the final stops of their campaigns.

The Australian prime minister earlier cast his ballot in his Sydney seat of Grayndler, while the opposition leader arrived in Brisbane to vote in his Dickson electorate.

Albanese and Dutton have spent the last five weeks crisscrossing the country in a gruelling election campaign, visiting up to three states a day and crucial marginal seats.

Labor sent out text messages to voters during polling day about the Greens' decision to not preference Labor in the ultra-marginal Victorian seat of Deakin, held by the Liberals.

"Preferences are critical in keeping Dutton out and this decision by Adam Bandt will put in jeopardy Labor forming government," the text message reads.

In the nation's capital, Canberrans took advantage of the city's democratic heritage by voting at Old Parliament House.

In Victoria, Kooyong MP Monique Ryan was being stopped by a journalist when a bird in a tree pooed on her.

The Liberals are desperate to wrest the seat back from the teal independent, which was previously held by former treasurer Josh Frydenberg.

At Mount Nelson Primary School in Hobart, a twist was added to the treats on offer in addition to the beloved democracy sausage.

Jacqui Lambingtons, eClair Chandlers and Brown's Brownies have made cake stall appearances as part of the fun.

Christine Palmer, a school parent managing the cake stall, said the kids had come up with the names.

Creative cake stalls have popped up all around the country, including a sign in Sydney "Make Australia Bake Again" and the "Crumpet of Patriots".

In Western Australia, which was crucial to delivering Mr Albanese his 2022 election win, independent MP Kate Chaney is fighting to hang onto her marginal seat of Curtin.

Casting her vote at a primary school in Perth's wealthier suburbs, she said the attack ads had been "thicker, faster and more desperate".

"The major parties are deeply threatened by the idea of a parliament that actually holds them to account," she told reporters.

"The hardest part is probably this part, the constant media scrutiny and the personal attacks ... this is the reason more people don't want to go into politics."

Albanese is aiming to become the first prime minister since 2004 to win back-to-back elections, while Mr Dutton fights to overcome history as the first leader since 1931 to unseat a government after one term.

Speaking at the MCG in Melbourne earlier on Saturday, the prime minister said Labor was after the "holy grail" of winning back-to-back elections.

He did the rounds on morning TV, giving a number of interviews.

Treasurer Jim Chalmers urged Australians to vote for stability in a period of global uncertainty.

"We are so grateful for the opportunity that the people of Australia have given us and we seek another term with humility," he said.

The final YouGov poll before election day shows Labor in the box seat to form majority government.

The poll, provided to AAP, has Labor ahead 52.2 per cent to 47.8% on a two-party preferred basis.

Albanese also leads Dutton 51% to 34% as preferred prime minister.

Labor went into election day with 78 seats, while the coalition had 57 in the 150-seat House of Representatives.

A majority of 76 seats is needed for a party to form government.
