NSW deaths push road toll to seven

The nation's Easter road toll stands at seven following two fatal NSW collisions.

The latest death was that of a cyclist, killed instantly when struck by a car on Sydney's north shore on Saturday afternoon.

Police said the male driver of the Mercedes sedan was uninjured but had been taken to hospital for mandatory blood and urine testing.

Two-and-a-half hours earlier, a man was killed when his car and a truck collided in the state's north at Tyndale.

The deceased driver is yet to be identified, while the man behind the wheel of the truck and his passenger both suffered non life-threatening injuries and were taken to Coffs Harbour Hospital.

Police are investigating the circumstances surrounding the crash and witnesses are urged to come forward. A report will also be prepared for the Coroner.

The deaths follow tragedies in Western Australia, Tasmania and Queensland over the holiday period.

Three of the fatalities were on WA roads and involved young men aged 17-20.

A Chinese tourist was killed in Tasmania and a Queensland woman died after being struck by a car.

The 67-year-old woman died on the way to hospital on Thursday after she was hit by a station wagon while crossing the road in Beaudesert, south of Brisbane.

On Thursday afternoon, a 17-year-old boy died after being thrown from a car which rolled several times on the Gnaraloo-Quobba Road near the West Australian town of Carnarvon.
