Citrus Australia represents the biosecurity interests of citrus producers and the industry. They are members of Plant Health Australia and signatories to the Emergency Plant Pest Response Deed. Their responsibilities include:

  • biosecurity planning and implementation at the national and farm levels
  • liaising with federal and state governments on trade issues
  • funding and supporting biosecurity initiatives
  • participating in national committees and response efforts in an emergency.

Industry overview

In 2013–14, citrus production (oranges, mandarins, lemons, limes and grapefruit) was valued at $446 million (LVP). In 2014, production of citrus was estimated to be 620,000 tonnes. Currently, there are about 28,000 hectares of citrus plantings nationally.

Citrus is the largest fresh fruit exporting industry in Australia with major export markets including Hong Kong, Japan, China, Malaysia, Indonesia, Singapore, the United States and New Zealand. Citrus fruits are grown commercially throughout Australia, with the exception of Tasmania and the Australian Capital Territory. Major growing areas include the Riverina (NSW), Central Burnett and Emerald (Queensland), Riverland (SA) and Murray Valley (Victoria/NSW). Production also occurs in WA and there are a small number of plantings in NT.

The Citrus Biosecurity Project, which is funded by Hort Innovation and jointly managed by PHA and Citrus Australia, continued through 2015, boosting the preparedness of the citrus industry for serious exotic pests.

Citrus industry biosecurity planIndustry Biosecurity Plan for the Citrus Industry

Biosecurity planning provides a mechanism for the citrus industry, government and other relevant stakeholders to assess current biosecurity practices and future biosecurity needs. Biosecurity planning identifies procedures that can be put in place to reduce the chance of pests reaching our borders or minimise the impact if a pest incursion occurs.

The Industry Biosecurity Plan for the Citrus Industry outlines key threats to the industry, risk mitigation plans, identification and categorisation of exotic pests and contingency plans. For a copy, please contact PHA on 02 6215 7700 or email

Biosecurity Manual for Citrus ProducersBiosecurity Manual for Citrus Producers

The Biosecurity Manual for Citrus Producers contains information to help producers to implement biosecurity on-farm. Manuals usually contain an overview of biosecurity, fact sheets to identify the high priority pests of a crop, tips on crop management, and how to manage people, vehicles and equipment to minimise biosecurity risks. Manuals also contain a biosecurity self-assessment list, and templates to record pest surveillance records and visitors.

More information about on-farm biosecurity for both plant and livestock producers is available from the Farm Biosecurity website.

Exotic pests (not in Australia)

The following is a list of high priority exotic pests of citrus. These pests were identified during the development of the Industry Biosecurity Plan for the Citrus Industry in consultation with industry, government and scientists. They have been assessed as high priority pests based on their potential to enter, establish, and spread in Australia (eg environmental factors, host range, vectors) and the cost to industry of control measures.

PHA has a range of fact sheets, contingency plans and diagnostic protocols relevant to these pests. Pest risk review documents are also available for some pests. Please contact PHA on 02 6215 7700 or email for more information.

Endorsed National Diagnostic Protocols are available from the National Plant Biosecurity Diagnostic Network webpage.
