The driver of the Barina, a 79-year-old man, died at the scene.
His 72-year-old wife was airlifted to St George Hospital where she died on Saturday.
The driver of the Camry, a 35-year-old man, suffered serious injuries and was taken to Wollongong Hospital for treatment.
A two-year-old boy, who was a passenger in the Camry, remains in hospital in a serious condition.
On Monday the 35-year-old was arrested at Wollongong Hospital and taken to Wollongong Police Station.
Officers from the Southern Region Crash Investigation Unit charged him with two counts of dangerous driving occasioning death and dangerous driving occasioning grievous bodily harm.
He was refused bail and will appear at Wollongong Local Court on Tuesday.
