A mother has been reunited with her teenage son after he went missing in thick bush land for 18 hours in South Australia last night.

“I didn’t want to let him go .. and I won’t let him go for a little while yet,” Hayley Good said as she was reunited with her 13-year-old Logan Good this morning.

Ms Good raised the alarm at about 6pm yesterday when the boy disappeared while walking ahead of his family towards Alligator Gorge car park in the Mount Remarkable National Park.
