A toddler who was hit by a car driven by her father was one of two people who died in tragic accidents at Lake Conjola on Australia Day.
The 17-month-old girl and her family, from the Sydney suburb of Rosemeadow – near Campbelltown – were holidaying at a caravan park at Lake Conjola.
Shortly after 3.30pm the father, aged in his 30s, got into his Holden Trax SUV to move it to a different spot.
It is understood the 17-month-old girl had moved behind the car, and her father could not see her as he started to reverse.
The father was taken to Milton Hospital for mandatory blood and urine testing.
Following the testing he was interviewed by detectives at Ulladulla police station before being released.
He has not been charged over the incident at this stage.
Around a half-an-hour later, emergency services were called to a boat ramp on Killarney Road at Lake Conjola, on the southern side of the lake.
A 28-year-old woman from Fishermans Paradise, just a few kilometres to the north, had fallen off a boat and into the lake.
She was then hit by the boat.
The woman was rushed back to the boat ramp where rescuers performed CPR but she was pronounced dead at the scene.
The skipper of the boat, a man believed to be in his late 20s, was uninjured and has undergone mandatory blood and urine testing.
Detectives plan to interview the skipper in the coming days.
A second man on the boat was also uninjured.
At this stage no charges have been laid over the boating incident.
Officers from South Coast Police District assisted by the Marine Area Command are investigating the circumstances surrounding the incident.
They are appealing for anyone who witnessed the incident to come forward.
People with information on the fatality in the water of Lake Conjola are urged to contact Crime Stoppers on 1800 333 000 or https;//nsw.crimestoppers.com.au
