Bill Shorten has returned from holidays and accused the Turnbull Government of having the wrong priorities for 2017.
"The Trans-Pacific Partnership is dead in the water," Mr Shorten told reporters at a factory in Dandenong, Victoria.
"Why on earth Mr Turnbull wants to tee off his year on a trade or treaty with Donald Trump who said he won't sign it is beyond me. It is a waste of time."
The Labor Party is signalling its focus for the year will be on domestic policies.
"I am here today because Labor intends to make, as its number one issue for 2017, the fight for Australian jobs," Mr Shorten said.
"We will be talking about building Australian first, making Australian first and employing Australians first."
