South Australia’s Riverland region is recognised as a fruit fly Pest Free Area (PFA) by several international markets.
Free of both Queensland fruit fly and Mediterranean fruit fly, the region is renowned for growing high quality fruits, vegetables and nuts, in particular citrus, stonefruit and almonds.
The PFA status allows produce from the Riverland to be shipped directly to these markets without the need for treatments, with benefits including:
- reduced costs and delays across the supply chain
- products that reach markets in a premium condition, often with a longer shelf life.
The Riverland’s PFA is maintained in accordance with the International Plant Protection Convention’s (IPPC) International Standard for Phytosanitary Measures (ISPM26).
Protecting the Riverland PFA from fruit fly
Watch and discover how we ensure South Australia's fruit fly free status and Riverland Pest Free Areas are protected.
Geographically, the Riverland is surrounded by dry arid-lands that are hostile to fruit fly. This environment prevents the natural spread of the pest from other Australian states and territories.
The greatest risk of fruit fly entering South Australia is through the movement of vehicles and people into the state. To reduce the risk of people moving fruit fly into South Australia and the Riverland PFA, strict quarantine controls are in place that:
- ensuring commercial produce is certified free from pests before entering the state or PFA
- restricting how fruits and vegetables can enter South Australia
- enforcing additional restrictions on fruits and vegetables entering the Riverland PFA.
Assuring the Pest Free Area is maintained
We are committed to activities and programs that protect the PFA and South Australia's fruit fly free status, including:
- Maintenance and monitoring of an extensive surveillance network of more than 7,500 traps across the state and over 100,000 site visits to fruit fly trap sites by inspectors.
- Biosecurity border controls: four quarantine stations located on major SA highways and more than 730,000 vehicles checked each year.
- Regularly serviced quarantine bins that are located at key entry points to the state for travellers to dispose of any fruit that could pose a risk to our PFA status.
- Random roadblocks are carried out on roads leading into the Riverland, where travellers are fined if found with restricted items.
- Industry engagement and coordination to ensure industry are proactive in their protection of the PFA.
- Employment of a dedicated Riverland Fruit Fly Coordinator to work with industry.
- Research and development to improve monitoring and control capabilities.
- Regular auditing of certified businesses importing fruit fly host produce into the state.
- Community awareness campaign to ensure the public and travellers know what they need to do to keep South Australia fruit fly free and how important this is for producers.
- A world-leading National Sterile Insect Technology (SIT) facility at Port Augusta. This technology was pioneered in South Australia. During an outbreak, sterile flies are released to mate with wild female fruit flies, collapsing wild populations in fruit fly affected horticulture growing regions.
What happens if fruit fly is detected
As a result of our extensive trapping and surveillance network we occasionally detect Queensland fruit fly in the Riverland. Detections are monitored closely and if an outbreak occurs, it is met with immediate and effective control processes that:
- meet international standards
- eradicate outbreaks and maintain domestic and international export pathways.
There have been no outbreaks of Mediterranean fruit fly in the Riverland.
