Over 100 Bodies Recovered After Flash Flood on Nepal-Tibet Border
A local tourist attraction known as Sammy the elephant seal has drawn intense community concern due to the escalating H5 bird flu outbreak in Portland. The male southern elephant seal has frequently visited the foreshore, port, and community gardens in an area now designated as a wildlife disease hotspot.
Winter Cold Sets Backdrop for Portland Outbreak
Carcass Management Strains Local Authorities
The situation in Portland has become severe since the first confirmed case of H5 bird flu emerged in the far south-west of Victoria at the end of July. According to the federal agriculture department, the region has recorded 17 confirmed events in crested terns, magpies, silver gulls, and ravens, alongside numerous suspected cases.
Local resident and Southwest Environment Alliance president Lynn Murrell described the beach conditions as pretty grim, noting an estimated 30 to 40 new sick and dying birds on the beach a day and raising public anxiety over carcass disposal and scavenging risks. A Glenelg shire council spokesperson acknowledged that the crisis has caused significant community distress, noting that state government guidance advises leaving the dead birds in place unless an unacceptable public amenity or safety risk requires council removal.
Gregarious Behavior Amplifies Seal Vulnerability
Marine mammal vulnerability to the deadly strain remains a pressing logistical challenge. According to Macquarie University professor Rob Harcourt, southern elephant seals are exceptionally gregarious characters that naturally invite community affection and naming. However, their social behavior presents severe transmission risks.
Harcourt explained that seals are thigmotactic, meaning they love to lie touching each other and recognize one another through nasal exchange by sniffing faces. These biological traits, combined with their extensive feeding migrations over 1,000 kilometres, heighten their exposure. While southern elephant seals breed primarily in large colonies on Macquarie Island, the species is listed as vulnerable under federal environment laws and faced a devastating toll when the strain killed more than 13,000 pups on Heard Island in 2025 and 2026.
Endangered Populations Face Rising Exposure
The threat extends beyond elephant seals to other vulnerable marine populations along the southern coast. According to Macquarie University’s Rob Harcourt, Australian sea lions—categorized as endangered—are of particular concern because of their playful, curious, and friendly nature, prompting him to state that he would be totally and utterly devastated if we lose them.
While volunteer wildlife carers from western Victoria travelled to Portland to humanely euthanize sick birds, and more than 100 marine mammals have been reported to the emergency animal disease hotline in Victoria this month, no marine mammals have been confirmed as positive cases in the state.
