The helicopter was tasked to a property near Narrabri about noon on Saturday, following reports a man, believed to be aged in his 50s, had been gored by a bull.

Initial information indicated he may have punctured a lung. 

It was later confirmed a 54-year-old man was flown to Tamworth hospital.

He sustained chest injuries and a punched lung, and was reported to be in a serious condition.

That afternoon, the Westpac Rescue Helicopter was then tasked to a motorcycle accident between Bingara and Narrabri in the Killarney Gap area.

Emergency services were also on the scene, responding to the accident.

About 5.20pm Saturday, a Westpac Rescue Helicopter spokesman confirmed that a 33-year-old man had come of a motor cross bike earlier in the afternoon. 

The man had been at a motor cross track in the Killarney Gap area.

He was flown to Tamworth hospital with leg and pelvic injuries, and was reported to be in a stable condition.
