Australia will file a formal complaint with the World Trade Organisation (WTO) after China imposed up to 218% tariffs on its wine last year.
China says the tariffs were increased because of trading malpractice, which Australia denies.
Australia says it remains open to engaging directly with China to resolve the issue.
China is the top market for Australian wine exports and wineries say they have been badly hit by the hikes.
The decision to take the dispute to the WTO was made after extensive consultation with winemakers, the Australian government said in a statement.
“The government will continue to vigorously defend the interests of Australian winemakers using the established system in the WTO to resolve our differences,” said Dan Tehan, minister for trade, tourism and investment.
China accuses Australia of a trade practice called dumping, which is illegal in international trade law.
