Prime Minister Scott Morrison says there won't be any deals done to secure the passage of laws setting up a new long-term drought fund.
Labor has baulked at the Future Drought Fund, which will be debated in parliament on Monday, because it draws on money from an existing infrastructure kitty.
The Australian Greens fear it will funnel money to the coalition government's "big corporate irrigator mates".
"Labor need to answer a simple question - will you support our farmers or not?" Mr Morrison has said ahead of the debate.
"Drought funding is not something we should be having to make deals on, it should be a no-brainer, something that should just get done.
"So there'll be no deals, just a simple request to vote for the bill that will provide for long-term drought resilience works. It's quite absurd that Labor have opposed it for this long already."
Mr Morrison said the government was able to fund $100 billion in infrastructure as well as the drought fund.
"There is not one road, there is not one dam, there is not one railway sleeper that has been taken away from our infrastructure program by going ahead with the Future Drought Fund."
Greens leader Richard Di Natale said the government has a record of funnelling money into pet projects.
If it was serious about the drought, it would have a comprehensive climate change policy, he says.
"You don't fix what is going to be a long-term problem of more severe, more frequent drought unless you tackle the central cause, and that is the breakdown of our climate," Senator Di Natale told the ABC Insiders program on Sunday.
