The head of the anonymous police tip-off line Crimestoppers says it has had its busiest three months since it began.
Lou Gardiner says in Crimestoppers' first 29 months of operation, the phone line took 22,500 calls.
He says in February alone, the line received an average of 37 calls a day, with 398 of them considered actionable.
Mr Gardiner says rather than the increase being a reflection of increasing crime rates, it shows communities are growing less tolerant of illegal activity.
He says 65% of the information from the public is about drugs.
