The woman was standing near a tree at her home when the lightning struck her and the tree. She was treated for a lightning strike to the chest and paramedics performed lifesaving CPR.
She was taken by CareFlight’s Rapid Response Helicopter Westmead Hospital in a critical condition.
At 5.24pm, a 29-year-old surfer was struck by lightning while leaving the water at Dee Why Beach. A specialist medical team and four ambulance crews were sent to the scene.
He was conscious and was taken to Royal North Shore Hospital in a serious condition.
Ms Parish praised the quick work of nearby citizens as being vital to saving lives.
“Both patients were 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,” she said.
“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.”
The weather in the area also caused power outages in several suburbs, with Ausgrid confirming outages in Beecroft, Epping, Dee Why, Manly, Curl Curl, Brookvale and Allambie Heights.
