The deal was announced by Prime Minister Tony Abbott who called it "a momentous and historic day" for the two nations.
The agreement was signed by Australian Minister for Trade and Investment Andrew Robb and his Chinese counterpart Gao Hucheng in Canberra today following a decade of negotiations.
"The China-Australia Free Trade Agreement (ChAFTA) will lock in existing trade and provide the catalyst for future growth across a range of areas including goods, services and investment," Abbott said.
"It will change our countries for the better, it will change our region for the better, it will change our world for the better," he said. "This agreement will give our nations unprecedented access to each other's markets."
China is Australia's biggest trading partner, with the two-way flow exceeding 160 billion dollars annually.
Noting that the leaders of the two countries have attached great importance to the signing of FTA, Gao said, "It is a milestone in bilateral relations."
Abbott said Australia's agriculture sector would also be able to capitalise on its well-deserved reputation as a clean, green producer of premium food and beverage products.
Tariffs will be progressively abolished for Australia's USD 13 billion dairy industry.
"Australia's beef and sheep farmers will also gain from the phased abolition of tariffs ranging from 12-25 per cent and all tariffs on Australian horticulture will be eliminated," the prime minister said.
Under the deal, the tariffs on cooking coal were also removed from day one, with the tariff on thermal coal being phased out over two years apart from tariff elimination on a wide range of Australian manufactured goods, including pharmaceutical products and car engines.
The agreement will enter into force after the completion of domestic legal and parliamentary processes in China and Australia, including review by the Australian Parliament's Joint Standing Committee on Treaties, and the Senate Foreign Affairs, Defence and Trade References Committee.
