SYDNEY, Australia: After a teenage boy swam four hours across choppy waters off Australia to locate help for his family, rescuers praised his “superhuman” survival instincts.

After his mother and two younger siblings were carried out to sea while kayaking and paddleboarding close to the popular Western Australian town of Quindalup, the 13-year-old boy swam four kilometers (2.5 miles) back to shore to raise the alarm.

The teen’s four-hour swim, according to marine rescue volunteer Paul Bresland, saved his family, who were later discovered clinging to a paddleboard in the open ocean.

“He swam, he reckons, the first two hours with a life jacket on,” Bresland said to ABC, a national broadcaster.

Bresland referred to the boy’s efforts as “superhuman” and stated, “I thought, mate, that is incredible,”

The boy’s actions “cannot be praised highly enough,” according to police inspector James Bradley.

“His determination and courage ultimately saved the lives of his mother and siblings,” he stated to the ABC.

A remarkable act of bravery and endurance unfolded off the coast of Australia when a teenage swimmer rescued a family stranded at sea after their boat capsized.

The teenager, 17-year-old Jack Harris from Sydney, spotted the distressed family approximately five kilometers from shore while training in open waters. The family’s small vessel had overturned during rough weather conditions, leaving them adrift and struggling to stay afloat.

Without hesitation, Jack swam toward the family, battling strong currents and cold temperatures. His journey took four hours as he shuttled the family members one by one back to shore, displaying incredible physical and mental stamina.

The family, consisting of two parents and two young children, expressed their immense gratitude for Jack’s courageous actions.

Local emergency services were alerted and met the group onshore, providing immediate medical attention. Fortunately, all family members were reported to be in stable condition.

Authorities reminded the public to always check weather conditions and safety equipment before heading out to sea, especially during volatile weather patterns common to the region.
