The pesticides authority has offered to pay its staff up to $55,000 in moving costs if they join its move north to Armidale - and stay for two years afterwards.
A document released to senators shows the Australian Pesticides and Veterinary Medicines Authority is also trying to keep its public servants ahead of its move from Canberra with three bonus payments averaging 6 per cent of their income.
The agency's plan to keep experienced staff emerged shortly before it released a review into its performance recommending it ask customers to pay more for its regulatory work and stop "low-quality" applications for approvals clogging its workflow.
It will pay moving costs for staff up to $55,000 but will claw back the money for every month after they've left the agency within two years of moving to Armidale.
The plan to keep its workers would put another $14,000 in bonuses in the pocket of an APS 5 level public servant, and the authority will pay travel and accommodation for staff visiting the northern NSW city to work there for three days and see the New England region.
Staff will also bank a $1000 disturbance allowance, or $1500 if they have at least one dependant and $500 more for every child who is a full-time student.
Labor agriculture spokesman Joel Fitzgibbon said the $55,000 reimbursement figure was exorbitant, and further evidence that the forced relocation was not working.
Renewing his call for new Agriculture Minister David Littleproud to stop the move, Mr Fitzgibbon said retention bonuses would not prevent people from leaving the agency.
"No strategy will make this pork barrel work. It's like trying to put a Band-Aid on a severed arm, it's past time egos and politics were set aside and this crazy idea pork barrel was stopped in its tracks," he said.
An independent review of the APVMA's performance, which deteriorated last year as on-time product approvals plummeted before a late recovery, made little mention of its move to Armidale but said the relocation may affect how it implements its recommendations.
Consultants Reason Group found low-quality applications for new products, a lack of incentives to complete overdue work, and conservative rules slowing registration had dragged its performance levels.
Work had grown more complex for its regulatory scientists and similar agencies overseas had not met their performance targets either, despite being able to stop the clock on their applications when asking clients for more information about their products.
The report urged the APVMA to focus on clearing its backlog of overdue assessments for pesticides and veterinary medicine products, and use external scientists more efficiently.
It also said the agency had begun work to improve assessment timeframes and to help the industry submit better quality applications.
Agency chief executive Chris Parker said it accepted all the report's recommendations, but there was no "silver bullet" to improving its performance.
"The priority right now is to prepare our people and operations for Armidale. So our focus is on implementing those recommendations that lay a strong foundation for the future APVMA operations in Armidale where further improvements will be made," he said.
The agency said it was making better use of legislative instruments, exploring earlier rejections of poor quality submissions, better managing its backlogs and lowering its sign-off of decisions to assessment teams.
Dr Parker said $25.6 million the Coalition government had given the APVMA to fund the move would cover the relocation reimbursements and retention bonuses.
"Both the retention and relocation policy seek to ensure that we maintain corporate knowledge from our experienced staff for as long as possible," he said.
"Our people are highly trained and capable, and it's in the best interest of the APVMA, industry and the community to retain their expertise working for us while we operate from Canberra."
Mr Fitzgibbon said the scope of the review, and Dr Parker, had ignored the impact the relocation was having on the authority and those who relied on it.
The APVMA's performance levels improved for another quarter, as its on-time assessment rate grew from 58 per cent to 74 per cent for pesticide and veterinary medicine applications in the three months to December, figures published this week showed.
The pesticides authority is trying to stop further staff losses following an exodus of scientists from its doors after the Coalition announced its controversial relocation, a project driven by New England MP and Nationals leader Barnaby Joyce. The move has drawn accusations of pork barrelling.
Twenty regulatory scientists and an additional 28 staff members, with 204 years' service between them, left the agency between July 2016 and February.
Clarification: A previous version of this story said that the APVMA's on-time approvals rate grew from 53 per cent to 72 per cent for pesticides and veterinary medicines in the three months to December.
