Rice

The Ricegrowers’ Association of Australia represents the biosecurity interests of rice 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 2014–15, rice production was valued at $253 million (LVP). The Australian rice industry is predominantly located in the temperate climatic region of the Riverina in southern NSW. A very small area of rice is also grown in northern NSW and rice growing is emerging as an industry in north Queensland. In the Riverina, the major varieties grown are temperate Japonica varieties planted in October and harvested from March to May of the following year.

The vast majority of Australia’s rice is exported to international destinations in Asia, the Middle East, and many nations in the Pacific. Market analysis indicates that there is demand across all market segments, both domestic and international, for 950,000 tonnes of paddy production annually.

Following the acquisition of a rice seed company in north Queensland by Ricegrowers’ Limited (SunRice), rice is being grown there in increasing tonnages. While still limited, commercial production continues to increase as varieties bred specifically for that environment and local management techniques are introduced to the cropping system.

Strict biosecurity measures have been put in place to ensure that any rice plant pests which may be endemic in northern Australia are not spread south to the major rice growing area in NSW.

The rice industry is covered by version 3.0 of the rice biosecurity plan.

Rice IBPIndustry Biosecurity Plan for the Rice Industry

Biosecurity planning provides a mechanism for the rice 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 Rice 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 admin@phau.com.au.

Exotic pests (not in Australia)

The following is a list of high priority exotic pests of rice. These pests were identified during the development of the Industry Biosecurity Plan for the Rice 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 admin@phau.com.au for more information.

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