The PM wanted voters to consider the wider issues affecting the entire nation.
"As we look around the country, there are clearly some regional and state-based factors in play," she told Channel Nine.

"I understand in some parts of the country there's disappointment with state Labor governments.
"Of course people can form their views about their state governments, have their say in their state elections. The national election ... is about who has the best policies and plans for the nation's future and particularly the economic plan to manage a $1.3 trillion economy.
"It's just a question really of people looking at what this election is about and making sure when they vote next Saturday, they're voting on the issues in the national election."
Labot renews attack on spending promises
Meanwhile Labor has renewed its attack on the coalition's spending promises warning the $30 billion in election commitments so far will blow a $3.6 billion hole in projected budget surpluses.
The attack came as Treasurer Wayne Swan admitted the latest opinion polls showed the government could lose power on Saturday.
Coalition on track to win 17 seats
A Galaxy poll of 4000 voters in 20 marginal seats, published in News Ltd papers on Sunday, has found the coalition is on track to win the 17 seats it needs for government.
"There's no doubt if that poll were repeated on polling day then Tony Abbott would become prime minister," Mr Swan told the Ten Network on Sunday.
A day before its official campaign launch in Brisbane, Labor is keen to emphasise what it sees as the coalition's lack of economic responsibility.
It has released its own summary of the coalition's "reckless election spending".
The government-estimated $30 billion in promises had been offset partly by announced spending cuts, leaving a $3.6 billion hole in the budget surpluses in 2012-13 and 2013-14.
"It's taken Mr Abbott less than one month to almost halve the budget surpluses," Mr Swan said.
Coalition eyes further savings
But the coalition says it will announce further savings during the final week of the campaign that will result in a bigger budget surplus than Labor in three years' time.
Prime Minister Julia Gillard, campaigning in Melbourne, will unveil a plan to rein in banks and credit providers from automatically raising credit card limits.
A re-elected Labor government would make it illegal for banks to offer regular credit limit increases unless consumers opt to receive them.
Credit card statements will have to include a section on how long it will take to pay off the credit card balance if the holder makes minimum payments only.
Opposition Leader Tony Abbott is campaigning in western Sydney where the coalition is hoping to pick up three seats from Labor.
