Henry Shepherdson, 38, jumped from the Whispering Wall tourist attraction with his nine-month-old daughter Kobi in a baby carrier on Wednesday afternoon.
Police said initial investigations revealed a history of domestic violence between Mr Shepherdson and Kobi’s mother.
Natasha Stott Despoja – the chair of Our Watch, a group working to end violence against women – said South Australians were angry and sad at Kobi’s death and what it said about how women and children were treated unequally in society compared with men.
She said Kobi’s death and that of Kelly Wilkinson in Queensland “exemplify failings in the system”.
“We know that there are regulatory, there are legal failings, there are gaps in the law,” she said.
“There are problems with enforcement, there are problems with women being believed.
“There’s problems with apprehended violence orders being enforced.
