Senior Labor figures have struck down internal concerns within the party that it is capitulating to the Coalition too often, warning colleagues not to buy into the "Greens tactic".
The comments came during a Labor party room meeting, where the party decided to support a government bill to stamp out vegan activists trespassing on farm land.
Two Labor politicians warned the party was being seen too often to roll over on major issues being pushed by the Coalition.
The party copped a flogging in June for voting for the government's tax cuts package, after its amendments failed to get up.
But Senator Penny Wong said colleagues should not buy into the "Greens tactic".
Leader Anthony Albanese also said there was nothing Labor about voting against the tax cuts, which would "put more money in the pockets of cleaners".
Mr Albanese also said the party had no obligation to protect "vegan terrorists".
The so called "farm invaders" bill would make it a crime to use a carriage service to incite someone to trespass, or to damage, destroy or steal property on farmland.
It comes after animal rights charity Aussie Farms created an online map earlier this year showing locations and details of farms.
The National Farmers Federation said at the time the bill would encourage trespassing on farmland.
But in a Senate report on the draft laws, Labor senators Kim Carr and Anthony Chisholm argued the bill was unnecessary and could have unforeseen consequences.
They also said the protections for whistleblowers were extremely limited.
