Maverick MP Bob Katter wants the science behind farm water run-off hurting the Great Barrier Reef to be double-checked.
Wanting to protect the sugar industry in his north Queensland electorate, Mr Katter has also called on the coalition to give the auditor-general money to scrutinise funding for scientific studies on the reef.
"What they are proposing with the regulations of reef run-off onto the Great Barrier Reef would make it impossible for us to keep our soil nutritional," Mr Katter told federal parliament on Wednesday.
The Queensland state government has proposed strict pesticide and fertiliser regulations, after studies demonstrated how the chemicals were hurting the reef.
Mr Katter's calls to the federal government effectively fizzled, with no other MP backing him up.
The rogue MP's motion comes a day after the Senate voted for a parliamentary inquiry to scrutinise the science around farm water run-off hurting the reef.
Queensland LNP senators James McGrath and Susan McDonald initiated the inquiry, which will look at the connections between farming in the catchment and water quality, along with laws around farm management, water quality and soil run-off.
Greens senator Larissa Waters said the government was at war with science and the reef would suffer for it.
The Great Barrier Reef Marine Park Authority last month identified agriculture as the "main pollutant source affecting the condition of the marine ecosystem".
