Turnbull was speaking at a commemoration dinner on retired aircraft carrier the USS Intrepid on Thursday night, which was held just hours after House Republicans successfully voted to repeal and replace the Affordable Care Act, better known as Obamacare.



In his opening his remarks, Turnbull said "it's great" Trump and House Republicans succeeded.

"It's always good to win a vote in the Congress, or the parliament as we call it," Turnbull said. "I've got to say, it's always satisfying to win a vote when people predict you’re not going to win it too."



"So keep at it, it's great."



The House Republican bill aims to overturn key parts of Obamacare, including allowing insurance companies to charge people with pre-existing conditions higher premiums.

The prime minister's apparent support for Trump's dismantling of the US healthcare law will raise a few eyebrows in Australia.

The Labor Opposition has been running a sustained political campaign against Turnbull for almost a year, claiming his government wants to dismantle Australia's healthcare system.

Labor's campaign, dubbed "Mediscare" by the media, has been pushing the idea that the Turnbull government wants to slowly privatise Australia's healthcare system.
