The humble fruit fly has brought Government and the horticulture industry together to fight the biosecurity threat.
A new agreement sets out the operational requirement for readiness and response activities as well as cost-sharing arrangements between Government and the affected industries.
It is the first under the Government Industry Agreement.
Fruit Fly Council chairman Philip Manson says the breakthrough after months of negotiation means the Government and the horticulture sector can work together to reduce the risk of the fruit fly.
"Fruit flies are one of the biggest biosecurity threats facing horticulture," he said.
"By working together under GIA, Government and affected industries can achieve far greater outcomes than working in isolation."
A fruit fly breakout could cost the horticulture industry up to $2.1 billion.
