Australia took over the chairmanship of the group that brings together the world's top economies on Saturday and stages the annual summit in Brisbane next November.
"I am determined the G20 won't be a talkfest. It must be practical and focused," Abbott wrote in The Australian newspaper.
"Our actions in Brisbane will be focused on removing the international impediments to trade, jobs and growth and identifying real solutions to issues such as lifting workforce participation rates and funding infrastructure," the Australian Prime Minister wrote.
The straight-talking Prime Minister pointed out that Australia, the 12th largest economy in the world, is currently in its 22nd consecutive year of growth.
Abbott outlined his government's effort to fast-track free trade agreements with South Korea, Japan, China, Indonesia and India to help spur growth.
"A stronger world economy means more jobs, more confidence and more tax revenue that can be used to pay down debt," he said.
He said that one area of focus would be infrastructure. "The world needs more infrastructure investment because building infrastructure drives growth and makes economies more productive in the longer term," he said.
"We need to encourage greater private-sector involvement and help capital markets better channel global savings to productive investments."
In the run-up to the G20 summit, Australia hosts meetings of the forum's finance ministers and central bank chiefs in Sydney in February and in Cairns in September.
