Rishab Iyer Missing in Nepal Floods: What His Partner Knows

Rishab Iyer, a 23-year-old Australian medical student, disappeared with his parents, Sreedharan and Lakshmi Iyer, and younger brother Rudhra while the family was on a Mount Kailash pilgrimage. They were among the people caught in the catastrophic flooding triggered by a glacier collapse near the Nepal–Tibet border on August 26, 2026. In the latest reporting available, the four remained unaccounted for. 710

What is known about the Iyer family’s last movements

Sarada Viswanathan, Iyer’s partner, last heard from him on the morning of August 26. She has used Apple Find My and Life360 records to reconstruct the group’s last known movements. The records placed members of the family outside or near the hotel where they were staying in the border area shortly before the flood. 7

One potentially important clue involved another person travelling with the group. According to Viswanathan, relatives of that traveller obtained information via Nepali authorities indicating that the person’s phone, using a local Nepali number, connected farther north later that day. That reported connection did not establish the person’s condition or exact location, but it suggested that telecommunications records may help identify where a missing traveller—or their phone—was after the disaster. 7

The Iyer family used Australian numbers, and Viswanathan said equivalent information had not been provided to relatives. 7

Why location and phone records matter in a rescue operation

In a disaster area where roads, bridges and buildings have been swept away, even a rough final phone connection can help responders prioritize a much smaller area. A cellular-tower record may indicate which network site a device contacted; app-based location history may offer a recent coordinate. Neither is a guarantee that a person is at that point, especially in a fast-moving flood, but the information can give search teams leads to investigate.

Viswanathan has argued that final location histories, tower connections and other phone records could help concentrate rescue efforts in specific valleys, roads, structures or debris fields rather than across the entire affected region. 7

Why Apple, Optus and Life360 limited access

The companies’ positions reflect the sensitivity of location and telecommunications data.

• Apple and Optus: Reuters reported that Viswanathan’s requests were declined on privacy and security grounds. Optus did not comment on an individual customer’s case, while Apple did not immediately comment. 7
• Life360: The company said a user’s approved “circle” can view the user’s latest location. People who are not authorized by the user must seek information through local authorities. 7

Those restrictions are designed to prevent unauthorized tracking and disclosure. In this case, the conflict is especially painful: relatives seeking data for a search may still not have the account authority or legal standing needed for a company to release it directly. The available reporting indicates that authorities, rather than families, are the channel companies expect to use for such requests. 7

What authorities and Viswanathan were doing

Viswanathan began compiling the group’s movements and launched a petition seeking additional Australian search assistance. 7

Australia said it had deployed drone specialists to Nepal and already had consular officials, humanitarian police and defence personnel involved in the response. The government also said it would provide telecommunications data to Nepali authorities and announced an additional A$3 million in humanitarian support, bringing its stated assistance to A$11 million. 7

Nepali police had searched the area where the Iyer group disappeared and said they would return if credible information emerged that tourists might be trapped. At the time of Reuters’ report on September 3, police said no Australian tourist had been rescued. 7

How many people were missing or dead?

The toll rose sharply as search and reporting efforts reached more areas, so early estimates should not be treated as final. On September 4, Reuters reported that more than 1,200 people had been confirmed dead and roughly 5,000 remained missing after the glacier collapse and floods. Australia said it had serious concerns for the welfare of 36 missing citizens.

Earlier reports recorded substantially lower totals—for example, about 390 dead and more than 1,400 missing across Nepal and Tibet on August 27—illustrating the scale of the uncertainty in the disaster’s first days.

For the Iyer family, the key unresolved question remains whether post-flood device records can produce a sufficiently precise lead for search teams. The reported phone connection from another traveller offers a reason to pursue that possibility, but it is not confirmation of survival or of the family’s location. 7
