Police are uncertain about Braakensiek's time of death.
A post mortem will provide more answers.
"On the surface, it all looked picture perfect. But of course, nobody’s life ever really is."
"Her marriage to Danny ended last year. She moved out of her beloved Bondi. Change wasn’t always easy."
Braakensiek and Goldberg broke up in April last year after 16 years together.
Following the demise of her marriage, the former model took to Instagram to speak about her hardships.
"Life's challenges have been deep, dark, difficult, demanding and down right scary lately."
"Everything seems to feel twisted and upside down at the moment... am I right?"
"Thanks to all of you who have carried me though this turbulent year."
"Time to breathe in the new beginnings and let go of the old... bring on 2019 already I say."
Her friend, Craig Bennett, spoke about his friend - the RUOK ambassador.
"Everybody saw her as this absolutely gorgeous soul, still modelling bikinis until recently," Bennett told the Daily Telegraph.
"When you have that dynamic when somebody is very frail and vulnerable deep down inside and then to have something as important to her as a marriage collapse it really knocked her for a spin."
"It kind of punched the wind out of her sails and plunged her into a dark place, all of which is evidenced in her social media threads."
