Police in eastern Victoria discovered a vehicle belonging to Lynette Joyce Bond, 68, abandoned along a trail in the Snowy River National Park near the New South Wales border on Saturday, the Australian Broadcasting Corp. reported.
A note was left in the car that said it had broken down on Wednesday.
A massive search involving police, rescue crews and volunteer bushwalkers all looking for Bond ensued and came to a close when a helicopter spotted the word "help" written on the banks of the Snowy River. Bond was then seen nearby, officials said.
Bond was airlifted to a hospital for a checkup, but is believed to be in good health, the Australian Broadcasting Corp. said.
