If you drive the Kwinana Freeway, your odds of finding a fine in the letterbox just got a lot shorter. Speed cameras across Perth's freeway network recorded 114,483 speeding infringements in 2025-26, and 96,544 of those came from the Kwinana Freeway alone.
That is a 216 per cent jump on the 36,232 detections recorded the previous year, according to figures reported by The West Australian.

Which Perth freeways caught the most drivers
The Kwinana Freeway accounted for roughly 84 per cent of all freeway detections. Some of the individual reads were serious. One driver was clocked at 103km/h in an 80km/h zone near the Mill Point Road exit about 10.40pm on 26 June, and another was caught at 115km/h on the same stretch just over an hour later.
The Mitchell Freeway climbed from 9,142 detections to 13,364. One driver there was recorded at 118km/h in a 100km/h zone near Karrinyup Road during peak hour, with two more caught at 123km/h and 125km/h inside an hour.
The sharpest rise was on the Graham Farmer Freeway, where mobile camera detections went from 735 to 4,575 in a year, an increase of more than 500 per cent.
Why the numbers jumped 216 per cent
The Cook Government says the surge mostly reflects more cameras rather than worse driving, noting new safety cameras were installed on the Kwinana, Mitchell and Graham Farmer freeways during the reporting period.
The network has kept growing since. Two new fixed camera locations on the Mitchell Freeway, at Vincent Street in Leederville and Karrinyup Road, became operational from 1 June 2026, joining the two existing fixed cameras on the Kwinana Freeway. Eight mobile safety camera trailers also work across the state.
The Government's own comparison points the other way on behaviour. Between February 2025, when the first cameras were switched on, and May 2026, detected speeding offences fell 51 per cent, seatbelt offences dropped by more than 85 per cent and mobile phone offences by 88 per cent.
What speeding costs you in WA
WA still has the cheapest entry-level speeding fine in the country at $100 for up to 9km/h over the limit, with no demerit points. It scales up quickly from there, reaching $1,200 and seven demerit points for more than 40km/h over.
The freeway cameras are not just watching your speed. Using a mobile phone while driving carries a minimum $500 fine and three demerit points, and failing to wear a seatbelt properly carries a minimum $550 fine and four demerit points. One camera can pick up all three.
What police say about the freeway detections
WA Road Policing Commander Mike Peters said even small increases in speed lift the risk of a serious or fatal crash.
"Speed remains a significant contributor to serious and fatal crashes on WA roads," he told The West Australian.
"Drivers are reminded to obey posted speed limits and adjust their driving to suit road and traffic conditions."
Money collected from safety camera infringements goes into the Road Trauma Trust Account, which funds road safety programs rather than general government revenue.
