Pests, weeds and diseases can travel onto a farm on boots, tyres, machinery and equipment. Biosecurity signs are a simple, visible way to tell visitors, contractors and delivery drivers that they need to check in before they enter, and to steer them to wash-down areas and the right entry points.
Australian farm industry groups and state agriculture departments all encourage property owners to have a farm biosecurity plan. Signage at the entrance is usually the first part of putting that plan into action.
What a farm biosecurity sign should say
- A clear instruction: for example "Please respect our biosecurity" or "Do not enter without permission".
- What visitors should do: call ahead, report to the house or office, or use a designated parking area.
- A phone number so visitors can let you know they've arrived.
- Your property name, which also helps delivery drivers and emergency services.
Our Stop – Please Respect Our Biosecurity sign and Visitors Please Respect Farm Biosecurity sign both let you add your own name and number.
Where to put biosecurity signs
- Every vehicle entrance, placed so drivers see it before they cross the grid or open the gate.
- Visitor parking areas, so contractors know where to stop.
- Wash-down bays, with a Vehicle Wash-Down Area sign.
- Restricted zones like animal housing, quarantine paddocks or waste areas, using a Biosecurity Area sign with custom text or a Biosecurity Waste – No Entry sign.

Best material for rural signs
Farm signs face sun, dust, rain and the odd bump from a ute. Aluminium is the toughest choice for gates and fence posts, with post mount holes or pre-drilled holes depending on how you fix it. Reflective aluminium makes entrance signs readable in headlights at night. For short-term events like field days, corflute with eyelets is a cheaper option.
A good size for an entrance sign is 450mm x 600mm or larger, so it can be read from a vehicle.
Boot wash signs: Disinfect your boots before entering or leaving this farm · Disinfect boots or shoes before entering these premises · Wash your boots before entering
