A man who was on parole and on drugs was caught driving at a speed of 169 km/hr through the airport tunnel on Tuesday.
The motorist, 42, who was behind the wheel of an Audi RS3, was weaving in and out of traffic, dangerously close to other vehicles, police said.
He was caught shortly before 11pm on Tuesday, when Botany Bay Highway Patrol was conducting stationary speed enforcement duties for westbound traffic on General Holmes Drive, Mascot.
General Holmes Drive, including the airport tunnel, has a signposted speed limit of 70km/hr.
The driver was stopped at Kyeemagh and when questioned, he said he "wasn't speeding".
He held an unrestricted NSW licence that he wasn't carrying at the time.
A roadside drug test was also conducted, which returned a positive reading to cocaine and methamphetamine.
He was arrested and taken to Mascot Police Station for secondary testing, which also returned positive readings.
The man was charged with driving at a speed dangerous to the public, class A motor vehicle exceeding speed of 45 km/rh and not carrying drivers licence. His licence was suspended on the spot.
Further charges relating to the drug testing are likely in the future.
