On 28 April 2018, a Boeing 737-800 exited the landing runway at Perth and without clearance crossed a lit red stop bar protecting the other active runway as another 737 was accelerating for takeoff. This aircraft was instructed to stop due to a runway incursion ahead and passed 15 metres clear of the incursion aircraft which by then had also stopped. The Investigation concluded that, after failing to refer to the aerodrome chart, the Captain had mixed up two landing runway exits of which only one involved subsequently crossing the other active runway and decided the stop bar was inapplicable.
