Sites with limited or no need for public access could be permanently closed by hard engineering methods (e.g. gates, fences, mounds, revegetation).
Sites that need to allow access to specific groups (e.g. utility providers, Rural Fire Service) could be closed using gates with keys provided to appropriate users only.
Sites needing to allow some public access can use soft engineering methods such as signage and surveillance devices.
Where sites are commonly experiencing dumping in small household loads (cars or 4WD), measures should be developed to reduce the likelihood of these vehicles crossing the barrier (i.e. steep mounds, cabled concrete blocks or bollard fencing and gates).
For a report on the effectiveness of a number of different access control measures see Illegal Dumping Deterrence Stage 1 Report.
