The body of a female cyclist has been found floating in mangroves along a river bank north of Sydney.
Emergency services attended Spike Milligan Bridge at Woy Woy on the NSW Central Coast on Sunday following reports of a woman's body found in shallow waters of the Brisbane Water.
A passer-by found the grim discovery in mangroves about 250 metres south of the bridge in shallow waters near a purple bicycle.
Other pedestrians and passing motorists also stopped to try to revive the woman as they waited for emergency services to arrive.
Police identified the body belonging to a 42-year-old woman.

A man and young boy believed to be the woman’s family later arrived at the scene looking distraught.
The shocked man cradled the boy while sitting on the footpath as he spoke to police, while emergency crews shielded the scene from passing cars, the Daily Telegraph reported.
A crime scene was established and is still being examined by specialist officers.
The incident sparked traffic chaos with vehicles banked up along Brisbane Water Drive for the rest of the afternoon.

A report will be prepared for the Coroner.
Police have urged anyone who was riding or walking along the cycleway and noticed the woman on the bike or has dashcam vision to contact Crime Stoppers on 1800 333 000.
