Safety chains from the top of Mount Warning have been ripped out, sparking fresh fears the iconic Tweed Valley climb may never reopen. Speculation has been building that the world-famous volcano also known as Wollumbin - which has been off limits since last March, would stay shut with mounting pressure from Indigenous groups for the mountain to be declared a sacred place similar to Uluru, which banned climbers in 2019. The NSW environment department insists the closure will be reviewed in May, but a leading climbing advocate who visited the mountain this week believes the summit climb s days are numbered after the removal of the chain section that helped hikers negotiate the final ascent to the top.
