Setting a national record, six out of 10 tips contained information strong enough to go straight to the police, the figures showed.
Drug dealers, suspicious activity, and traffic offences were some of the highest reports.
Cases are promoted weekly through various platforms, such as social media, print, radio and television.
WA Police Sergeant Nathan Gilmour said the force has had a 70 per cent success rate with people being identified and charged.
“The community possess a level of local knowledge that the police can’t always see on their own, and that partnership is how effective policing works,” he said.
Information is still coming in on more than 3000 open cases, including significant unsolved crimes like the disappearance of Sarah Spiers.
“We are still receiving information to this day to assist investigators with finalising that matter for the families,” Crime Stoppers WA Sergeant James Baker said.
Tips can be made by phone or online, and can be anonymous.
“No footprint is left when that information goes to police,” Crime Stoppers WA chief executive Vince Hughes said.
Online tips now make up 70 per cent of the reports that come in, while phone calls make up the remaining 30 per cent.
Police are urging anyone who may have information to contact Crime Stoppers.
