Agriculture minister Murray Watt said the findings of a recent report commissioned into the performance of the Australian Pesticides and Veterinary Medicines Authority (APVMA) left him with no choice but to seek to investigate matters further.
"The findings handed down in the Clayton Utz report in regards to things like workplace culture and chemical industry capture (of the APVMA) were concerning," he told the Australian Grains Industry Conference when discussing the national regulator for approving farm chemicals last week.
"I don't have a closed mind to what is happening at the APVMA but when you are presented with a report like this you have to take action," he said.
"We do not want to see an erosion of the APVMA's position as independent, science-based regulator."
"It is not in anyone's interest to have a regulator without credibility, whether that is consumers, the ag sector or our overseas markets, it is critical the APVMA maintains its independence and we expect the outcomes from the evaluation of the Clayton Utz report by Ken Matthews will enshrine that."
Mr Matthews was commissioned earlier this month by Mr Watt to conduct a rapid evaluation of the findings of the report and to provide advice about matters such as the legal structure of the regulator.
His opposition counterpart, shadow agriculture minister and National Party leader David Littleproud disagreed, saying he had concerns about the government approach to the APVMA.
"CropLife Australia is a strong advocate for its industry but I've never seen them influence APVMA adversely," he said.
He said he did not believe the APVMA's much-scrutinised move from Canberra to Armidale in northern NSW, authorised by former ag minister Barnaby Joyce, had impacted the regulator's performance.
He said improvements in completing applications within the required time frame rose from 54pc to 96pc done on time showed the APVMA was working at a practical level.
"It demonstrates regional Australia can perform just as well when given a chance."
"My message to the government is to stay away from the APVMA and let them do their job - we don't want to go down the European path where government is involved in regulatory decisions."
"The system in place has served the nation well and is regarded as a world leading model."
