Prime Minister Scott Morrison is not expected to see the Governor General to call a federal election for at least another week.

9News has confirmed Mr Morrison will not announce the date of the looming ballot until at least next week, despite speculation it may be called tomorrow.

Opposition leader Bill Shorten has appeared less than impressed with discussions regarding possible election dates.

“If the Prime Minister wants to play games about when he calls the election, I’m just not interested,” he said.

Mr Shorten’s comments come as his crackdown on issues like negative gearing could be harming his election prospects for the upcoming vote.

A leaked poll obtained by 9News in the marginal western Sydney seat of Lindsay has shown that just 36 per cent of seniors plan to vote for the Labor Party in the election, while 48 per cent will vote Liberal.

9News understands a dozen seats in NSW have been polled recently, with Labor trailing behind the Coalition – including in seats with voters aged over 65.

“We want to make sure when you need your health care system - and people over 65 need it more than any other age group – we are going to make sure this system is there for you,” Mr Shorten said.

In the seat of Lindsay, currently held by Labor, the leaked poll has the party behind the Liberal Party 55-45 and more than 10 per cent of people are tipped to vote for One Nation.

Despite those figures, Mr Shorten may be able to win the federal election with seats solely in Victoria, where even the safest Liberal MPs are facing threats from Opposition candidates.

The leaked poll also comes after Bill Shorten today outlined plans to boost specialised cancer nurses across Australia, saying he wants to employ an additional 42 prostate cancer nurses nationally.
