Ahead of the May 21 poll, Labor sees its protection of Australia’s cherished universal healthcare scheme as a key differentiator between it and the governing Liberal National coalition, which bills itself as superior on economic management and border protection.

Labor seized on Medicare as a key issue after Morrison said yesterday that he would appoint Anne Ruston as health minister if he is returned to office. Ruston several years ago described Medicare as unsustainable.

“This is a health minister, now designate if they’re successful in the election, who we know will undermine Medicare, who has said that the current model is not sustainable,” Labor opposition leader Anthony Albanese told reporters in Brisbane.

Campaigning in Perth to announce investment in two new navy patrol boats, Morrison insisted that there would be no cuts to Medicare if his government were re-elected.

“She (Anne Ruston) said yesterday there would not be any cuts and I would repeat that today,” he told reporters.

Morrison turned attention to asylum seeker policy, saying the new patrol boats would play an “ongoing and important role” in Australia ‘s border protection capabilities, while also criticising Labor for its past approach on the issue.

“When Labor abolished temporary protection visas in 2008, the armada of people smugglers’ boats came to Australia and that was the launching point, and I note that people smugglers are very aware of my resolve,” Morrison said.

The comments come after Albanese, earlier in the campaign, was forced to clarify Labor’s stance on border protection after mistakenly saying that it aligned with that of government.

Meanwhile, a new election poll released today showed a turnaround in support for Morrison, with the Liberal leader now ahead of Albanese as preferred prime minister.
