The page was set up by a member of Bruna's family and aims to raise €30,000 to return the body of the young woman back to her municipality of Formiga.
The body of the 28 year old was discovered at an apartment on Liberty Street in the city at 6:30am on Sunday.
Efforts were made to revive her, however she was pronounced dead at the scene.
A family liaison officer has been appointed and consular assistance will be given to repatriate her body to Brazil.
A vigil to pay tribute to Bruna will be held at the Lough on Sunday morning at 10am- organisers have asked people attending to wear white and to bring candles and white roses.
Meanwhile, a man has appeared in court charged with her murder.
29 year old Miller Pacheco of Room 3, Number 5 Liberty Street, Cork City appeared at a special sitting of Cork District Court yesterday evening.
He was remanded in custody and is due to appear before the court again next Monday.
