"[The cave] is approximately 500 metres from any vehicle," he said.
Safety lines were secured to the cave by the fire service and emergency services were delayed as they waited for a CaveSAR team to arrive.
Sergeant Mark Kirkwood was thankful the incident had a happy ending but warned others to be prepared when going into bush.
"It's crucial to be prepared when going into bush, the West Coast has numerous caves and mineshafts," he said.
"It's important to keep an eye on the weather, wear appropriate clothing and make sure too you are with a companion.
"Police would like to thank volunteers who showed up at short notice."
