Health minister Greg Hunt has announced the government is extending its investment in MRIs with 50 licences.
Announcing the investment on World Cancer Day, Mr Hunt said it builds on the first ten locations announced in September last year.
The government also opened a competitive public application process for the location for a further 20 Medicare eligible MRIs. Mr Hunt said this triggered "overwhelming demand" and 490 applications.
He said the government will now launch a competitive public application process for the locations for a further 20 Medicare eligible MRIs.
"I am pleased to announce that our Government will invest a further $150 million, bringing the total investment to $375 million over the forward estimates and delivering 50 MRI licences nationally," he said.
Shadow health minister Catherine King has announced a Labor government will fund 10 new MRI licences for public hospitals around Australia and a further 10 licences through an application process.
