Jordon Matthew Delaney, 23, of the tiny township north of Batemans Bay, appeared via audio-visual link on July 29 in Goulburn Local Court.

He pleaded guilty to three counts of police pursuit.

The chase ended when road spikes were placed on the Monaro Highway west of Nimmitabel.

Police said the pursuit began about 12.20pm on June 19, at Morans Crossing, north west of Bega, on the Snowy Mountains Highway, when police clocked Delaney driving a BMW 3 convertible at 143km/h.

Police pursued for a short distance, but stopped due to the danger.

The vehicle was seen near 18 Mile Creek near Bemboka and another pursuit initiated. The car fluctuated between speeds of 130-165km/h and crossed onto the other side of the road to overtake vehicles.

Through Bemboka, the vehicle was clocked at 100km/h in the 60km/h zone. Delaney increased speed to between 120-145km/h as he continued toward Brown Mountain. Police terminated the pursuit on the mountain.

At about 3pm, police saw the car travelling north near Bombala and resumed the chase for a short distance.

About 15 minutes later the car was seen travelling west through Nimmitabel and road spikes were set up at Rock Creek on the Monaro Highway.

Delaney was arrested and taken to Cooma District Hospital for blood/urine samples and a health check.

Delaney's solicitor on July 29 requested an adjournment for a Justice Health Report.

Magistrate Geraldine Beattie adjourned the matter to September 23 in the Goulburn Local Court for sentence.
