A report from the Victorian Coroner released on Wednesday, revealed 27 Aboriginal and Torres Strait Islander people died by suicide in 2024.
The figures are a 42 per cent jump since 2022, with the average age of death for men being 37 and 29.6 for women.
Some 56.6 per cent of Indigenous people who died by suicide from 2020-2024 were under 35.
This was compared to 30.2 per cent of non-Indigenous people who took their own lives.
In the four years until 2024, one third of First Nations suicides were in men aged 25-34, while the most common age for women was between 18-24.
The analysis also revealed a geographical divide, with 54.9 per cent of suicides in First Nations peoples in regional areas and 45.1 per cent in metropolitan areas.
This contrasts with the rest of the population, where two thirds of suicides occurred in metropolitan areas.
Stressors included diagnosed or suspected mental health conditions, interpersonal concerns, substance use, exposure to family violence and contact with the justice system, court data revealed.
State Coroner Judge John Cain said more conversations were needed at both a government and community level to save lives.
"It is deeply concerning that First Nations people in Victoria continue to pass by suicide at a rate almost three times higher than the non-Indigenous population," he said in a statement.
"It is critical to ensure proper supports are in place to drive down suicides in these communities."
Jessica Gobbo, from the court's aboriginal engagement unit Yirramboi, said it was vital to release up-to-date information so culturally safe supports can be developed.
"My heart goes out to all the Aboriginal and Torres Strait Islander communities disproportionately affected by suicide in Victoria – more work is needed to understand why and how these passings can be prevented," she said.
