The woman has yet to be formally identified but is believed to be 38-year-old Brazilian National, Cecilia Haddad, who lived in Ryde.
Ms Haddad had worked for a mining company in Western Australia before she moved to NSW in 2016 where she worked as a logistics manager for a freight company. She had also recently started her own business.
“By all accounts, Cecilia enjoyed an active social life and had made a large circle of friends during her time in Sydney,” Det A/Insp Sim said in a statement by police.
“Concerns were raised for her welfare after she failed to attend various appointments on Saturday (28 April 2018).
“Police spoke to a number of friends and associates in those initial stages, who described it as completely out of character.
“So far, we have been able to establish Cecilia went to a barbeque on Friday night and then spoke to friends on Saturday morning, but her movements after that time are unknown.
“We’ve been told her vehicle was seen outside her home on Saturday afternoon, so we are very keen to speak with anyone who may have seen her or her vehicle after that time.”
Haddad's body was found fully clothed by two kayakers around 10:15 on Sunday morning.
Results from a post mortem are expected to come in today which should hopefully provide some answers surrounding the circumstances of her death.
In the meantime police are treating the death as suspicious and are appealing for anyone with information to come forward.
