Shorten pledges health boost in Mayo visit

The federal opposition has committed to cut medical costs for thousands of people in the Adelaide Hills, in leader Bill Shorten's first foray into Mayo ahead of this month's by-election.

Mr Shorten said the opposition would support the provision of a new Medicare-rebatable MRI licence for Mt Barker to remove the need for patients to travel into the city.

"This is a practical, good news story for the thousands of people who live here. Why should people have to drive all the way to Adelaide to get an MRI scan and claim it back on Medicare," Mr Shorten told reporters on Friday.
