The grids are composed of spaced metal bars, which need to be at least 2.7 m in width in accordance with the Department of Main Roads specifications. The bars are at 220 mm centres, and the depth for the grid is 900 mm.

Grid Complexes

Grid complexes are used instead of grids when the volume of traffic on major highways becomes too great to maintain a grid at a reasonable cost. A rabbit-proof safety fence is erected on both sides of the road, as close to the road as possible, and the length of the fencing complex needs to be a minimum of 100 m, with a 2.7 m-wide 'painted grid' across either end of the complex. The 'painted grid' is there to deter movement of stock along the road corridor, within the complex.

Where possible, a tunnel under the road, on the dirty side of the rabbit-proof fence, is installed to allow rabbits and other small animals to cross under the roadway.

For a rabbit to pass through the narrow opening on the road, with such a high volume of traffic, is considered a minimal risk. The likelihood of the rabbit surviving the passing traffic is very low.
