Two people have been rescued from a hillside near Forsyth after falling from a scenic overlook off Highway Y.
Rescue teams took both victims by boat to a helicopter pad to be treated, and one was airlifted to a local hospital.
Both have apparent serious injuries.
A third person also fell down the bluff, but walked back up.
Fire crews say the sightseers crossed over the guardrail to get a better look and lost their footing.
