Preventing the introduction and spread of diseases, pests and weeds onto your land is one of the most things a landholder can do. Taking biosecurity risks seriously means making it part of your farm management, and making those practices second nature.
Using this simple online toolkit, you can create or update your own farm biosecurity plan. There are lots of useful templates and checklists on the site, relevant to a range of farm types.
The NSW DPI website also has some excellent information and resources, including detailed information about your responsibilities in biosecurity.
