Two people have been struck by lightning in Sydney within a span of just 10-minutes.
The first strike hit a 71-year-old woman in the chest outside her home on Bay Road in Arcadia at 5.14pm.
Four NSW Ambulance crews responded and performed life-saving CPR before rushing her to Westmead Hospital in a critical condition.
Ten minutes later, NSW Ambulance responded to a call-out at Dee Why Beach.
A man in his 20s was struck by lightning while leaving the water after going for an afternoon swim.
He was given CPR by a friend before four crews arrived.
They then started CPR and took the man to Royal North Shore hospital. The friend was also taken hospital with jaw pain.
NSW Ambulance Duty Operations Manager Carolyn Parish said the two incidents so close together was "extraordinary".
"This is the first time I have ever come across two lightning strikes within 10 minutes - it's terrifying," Ms Parish said.
"Paramedics had to work quickly at the scene – they want to get in there and do whatever needs to be done to save a life, often putting their own safety as risk."
She said paramedics at both Dee Why and Arcadia worked tirelessly on the patients and went to extreme measures.
"(They) did absolutely everything they could," she said.
"Both patients where firstly assisted by bystanders who commenced CPR prior to paramedics arriving. This is outstanding and they've got to be proud of the effort they made to help out in a tense and distressing situation.
"How you react to being hit by lightning depends on the circumstances and where you have been hit – most people however will go into cardiac arrest so those first moments of CPR are vital."
"We really need the public to take extra safety in these extraordinary fire conditions that are driving lightning strikes across the state."
