A kangaroo that had been hit by another vehicle had come through the windscreen of the family car, seriously injuring her mother and her younger sister.

According to the citation from Ambulance NSW, Rachel ran to the vehicle that initially hit the 'roo to borrow a phone to call her father and then instructed the phone's owner to call an ambulance.

"Rachel showed such bravery for a girl her age. She was suffering neck and back pain, but all the time she was concerned about her mother and sister," Dubbo-based paramedic Leanne Riley stated in the citation.

None of us would really know how we would react in a similar situation - unless [to state the obvious] we're in an accident.

Take for example the actions of three nippers [13-year-old surf lifesavers] who raced to the aid of two women who were swept off rocks near Avoca Beach just north of Sydney on Wednesday.

The boys were in the water training for their surf rescue certificate when they found themselves in a real rescue operation.

Unfortunately one woman died but the boys helped to rescue the other woman.

So well done to those young people, your selfless actions have helped others in dire need.
