Country's youngest MP Wyatt Roy backs working until 70 At 23, Federal Member for Longman Wyatt Roy is the youngest MP in Australia. This week he has backed a the Productivity Commission's recommendation to lift the retirement age from 65 to 70. Picture: News Limited Source: Supplied FEDERAL Parliament's youngest MP has urged the Government to consider raising the retirement age to 70. Wyatt Roy, 23, says people of his generation will pay more in taxes as the population ages and older people should work longer to help share the cost. "The question is about where the retirement age is set and given that people are living longer, I think it would be fair to expect that at some point they will retire later," he writes in an opinion piece for The Courier-Mail. Apart from enticing people to stay in the workforce longer, Mr Roy said the Government should do more to boost retirees' savings to reduce the burden on future taxpayers. "People must be encouraged to secure their own financial security across the long-term," he said. As a government, we need to ensure superannuants are getting the best possible deal. The Queensland MP's comments come after the Productivity Commission last week recommended lifting the retirement age from 65 to 70, which would save $150 billion over 50 years. Health and aged-care costs are forecast to soar as retirees live longer and the number of working-age taxpayers falls. Those left in the workforce face 21 per cent increases in their taxes to pay for the gap in costs from the ageing population, the Productivity Commission warned. The pension age is due to rise from 65 to 67 by 2023. A report by the Grattan Institute this week went even further and called for a ban on retirees accessing superannuation or the pension before they turn 70 to encourage people to work longer. Treasurer Joe Hockey has rejected the Productivity Commissions' calls but Mr Roy said there should be an open debate about the ageing population. The reality of our ageing population is that my generation will be paying to support the retirement of the previous generation on an unprecedented scale. The Productivity Commission proposals sparked a backlash from unions and welfare groups, which argued older people are often discriminated against in finding work and faced increased risk of injury. But business groups have backed the proposal, arguing it would help guard against future tax rises.
