An injured woman had to be rescued from the Great Ocean Walk near Port Campbell on Wednesday with a paramedic being winched in to help.
The alarm was raised about 4.30pm but the signal was first sent to the United States before being relayed to emergency services via Canberra.
Port Campbell Sergeant David Banks said officers didn't know how serious the incident was until they reached the woman after a three-kilometres hike.
He said the Melbourne woman, aged in her 30s, had a "decent gash" on her leg after falling off the walking track. The air ambulance had planned to winch her to safety, but the area was too dense with trees, he said.
However, they were able to drop a MICA paramedic nearby who Sergeant Banks said was able to "bush bash" his way to the injured woman.
SES crews arrived and were able to wheel the injured woman out on a stretcher before she was taken to hospital with minor injuries.
The injured walker raised the alarm on Wednesday afternoon which registered first with Garmin in the United States and triggered the emergency response back here in Australia minutes later.
An SES spokesman said the walker slipped while walking along the Great Ocean Walk east of Devils Kitchen campsite near Moonlight Head.
"There was no vehicle access due to the narrow track," the spokesman said.
People who plan to go bush walking are asked to fill out a trip intentions form.
The form should be left with a friend or family member, who will raise the alarm if the walker hasn't returned when they were expected to.
