South Australian police are investigating a heart-wrenching double tragedy that unfolded beneath the dramatic cliffs of Port MacDonnell. On Monday, July 27, 2026, the bodies of 36-year-old Helena Wright and her 23-month-old daughter were discovered floating in the ocean off Cape Northumberland, a remote stretch of coastline in the state’s Limestone Coast region. Her three-month-old son remains missing, and authorities have now called off the search, stating the infant could not have survived the days that have passed.

The discovery was prompted by a member of the public who reported a white Isuzu MUX vehicle abandoned with its engine still running near the cliffs around 11:15 a.m. Police quickly attended the scene. Upon arrival, officers spotted the body of an adult in the water, followed shortly by a second body that appeared to belong to a small child. Local fishermen assisted emergency crews in retrieving both bodies.

Helena Wright, originally from Estonia and living in the small community of Compton near Mount Gambier, had been a stay-at-home mother known to neighbours as bubbly, kind, and deeply religious. She and her family were described as private but always ready to chat and help others in the tight-knit area. Neighbours spoke warmly of her love for gardening and her talent for crafting children’s clothes, while noting that the family never displayed raised voices at home.

The incident is now being treated by South Australia Police as a suspected murder-suicide. Superintendent Trent Cox, in charge of the Limestone Coast region, confirmed that the family’s husband and father of the children had been spoken to. “Based on the evidence currently available, the matter is being investigated as a murder-suicide,” he said. “There is no information to suggest that any person other than the mother and her two children were involved.”

One of the most haunting details has emerged: Helena Wright attended Mount Gambier Police Station on Sunday, July 26, where she spoke with officers. A welfare check at her home on Monday morning — prompted by a friend’s call — found no one present. The same day, police received reports of the abandoned vehicle. These steps show the family sought help only hours before the tragedy.

Emergency services launched an immediate and extensive land, sea, and air search for the missing three-month-old infant. Volunteer groups, the South Australian Police, State Emergency Service, and aerial drone teams combed the shoreline and surrounding waters. However, challenging conditions — including high winds that prevented water assets from operating — severely hampered efforts. Police divers and specialists examined the area, but the search was suspended on Wednesday afternoon.

“The reality is, after three days, the chances of finding the baby alive are zero,” Superintendent Cox said. “The infant could not have survived the period of time that has elapsed, either in the water or on land. A range of factors, including the search environment and prevailing weather conditions, significantly reduce the likelihood of locating the infant in the immediate term.”

While formal search activities have ceased, police will continue shoreline monitoring and inspections in the coming days and weeks. The coroner will be informed, and a full report prepared.

The tragedy has shocked the community. Premier Peter Malinauskas described it as heartbreaking, especially given the ages of the victims. Police have provided psychological support through counsellors and medical staff in Mount Gambier, reminding residents to wrap their arms around one another and check on loved ones.

As the investigation continues under coronial oversight, the focus remains on the family’s welfare. Helena Wright’s husband has been kept informed, and authorities urge the public to respect the family’s privacy.

This devastating incident at Port MacDonnell has left a profound mark on the small South Australian community. While the exact circumstances are still under investigation, the heartbreaking loss of a mother, her toddler, and her infant son serves as a reminder of the fragility of life and the importance of reaching out for help when struggling.

The full story highlights how quickly a seemingly ordinary day can turn into one of the most tragic events in the region’s history. Police continue to offer support to anyone affected by the loss.
