The Coalition government has urged voters to look at the "facts" of Labor's tax figures amid claims they are running the dirtiest campaign in 20 years.
Coalition campaign spokesman Simon Birmingham said Australians face "$387 billion in higher taxes" under a Labor government.
It follows an explosive claim from Opposition Deputy Leader Tanya Plibersek on Sunday morning that Scott Morrison is running a campaign "full of lies about Labor's policies".
She also said it's the "dirtiest and most negative" campaign she has seen in 20 years.
Mr Birmingham told reporters the Labor Party is attempting to "create smear or distractions on the side".
"The simple choice for Australians at this election is do they want to pay $387 billion in higher taxes?"
"These are facts clearly in Labor party policy, even if Bill Shorten evades actually talking about [them]".
Labor on Sunday unveiled a plan to deliver free dental care to three million pensioners and seniors, while also promising a $4 billion childcare package.
Mr Shorten says 887,000 families will see childcare fees lowered by up to $2,100 per child.
Mr Birmingham, however, warned these promises come with higher taxes.
"With the Labor party there are so often promises to spend, spend, spend, but the consequence is Australians pay higher tax," he said.
"It's a tax, tax, tax equation from Labor."
