A young boy was also assessed for minor injuries but did not need to go to hospital.

“This was just a tragic scene to attend. These women were simply in the wrong place at the wrong time when this storm hit,” NSW Ambulance Inspector Christie Marks said in a statement.

“As you can imagine the patients had multiple injuries after being hit by falling branches and other debris.

“The strength of the storm is evident in the destruction it caused. Given the size of this tree it’s remarkable that there weren’t more people injured.”
