Scott Morrison is continuing his attacks on Labor's economic policies but the prime minister is also facing questions about controversial preference deals.
He will also have to address revelations at least one of his Liberal MPs met a far right activist at a rally in Perth in 2018.
Mr Morrison is in Perth on Wednesday to announce $16 million for a new soccer training centre and $10 million to help seniors combat loneliness.
On Tuesday he spoke to crowds and voters in the street about Labor's handling of the economy, arguing the opposition doesn't know the details of their own policies.
"If you can't manage money, you always end up spending more of it, and you certainly end up wasting more of it," Mr Morrison told a crowd in the Labor seat of Cowan.
But Opposition Leader Bill Shorten said stagnant inflation and a possible interest rate cut showed the economy isn't working as it should.
"This government's economic record is pretty bloody hopeless. Let's just call it as it is," the Labor leader told reporters on Tuesday.
Mr Shorten will be in Adelaide on Wednesday to announce the Spencer Gulf as a renewable energy zone, which will see it benefit from a $5 billion Labor fund.
The Labor leader made the same announcement for WA's South West earlier in the week.
Mr Shorten has also attacked the coalition for doing a preference deal with Clive Palmer, who owes taxpayers and his workers more than $70 million.
But Mr Morrison said Labor put Mr Palmer's party above the Liberals on their how-to-vote cards in 87 lower house seats, including putting it second in two Tasmanian seats.
He also distanced himself from the Nationals' decision to preference One Nation.
Nationals leader Michael McCormack argued One Nation has policies more similar to his party than Labor or the Greens.
Mr Morrison will also face questions after far right activist and convicted criminal Neil Erikson alleged he met Liberal MPs Andrew Hastie and Ian Goodenough at a rally supporting white South African farmers.
Mr Hastie originally refused to answer questions about it on Tuesday, before saying he was "confident" he had not met the activist.
Mr Goodenough also originally said he spoke to Mr Erikson for a few minutes, but later clarified Mr Erikson bailed him up on the street
