The Cosgrove Volcano Chain is one of its kind

Have you ever wondered what gives Cape Hillsborough it’s natural beauty? The answer will surprise you, because this wonderous piece of paradise is formed as a result of an extinct Volcano Chain, with Wedge Island being it’s northeastern most point.


The Cosgrove Volcanic Chain is a chain of extinct, ancient volcanoes that are about 34 million years old. The Volcanic Chain is unique for many reasons, the chief among them being its length.

As Associate Professor Rhodri Davies of the Australian National University’s Research School of Earth said, this Volcanic Chain is unique.

“It’s the longest continental track on Earth. We realised that the same hotspot had caused volcanoes in the Whitsundays and the central Victoria region, and also some rare features in New South Wales, roughly halfway between them,” Professor Davies said.

“The track is nearly three times the length of the famous Yellowstone hotspot track on the North American continent.”

The track begins at Cape Hillsborough, which is already home to one of the most unique experiences in Australia. Every morning, wallabies and kangaroos come down to the beach at Cape Hillsborough to gather and eat food, making it one of the most unique sights in Australia.

Cape Hillsborough Nature Tourist Park Owner Renee Atherton said the volcanic chain was the reason for the geographical diversity in the region.

“The Cosgrove Volcanic Chain has helped in the formation of the natural wonder that is Cape Hillsborough,” Mrs Atherton said.

“It has helped create the diverse topological terrain that attracts tourists and wildlife alike.”

The Cosgrove Volcanic Chain extends all the way through the Mackay and Isaac Regions before heading south to Victoria, with the Peak Range mountains also consisting of volcanic plugs.

Mackay Tourism CEO Tas Webber said the volcanic chain provides both the Mackay and Isaac Region with some exclusive experiences.

“The volcanic chain provides tourists with some unmatchable experiences in both the Mackay and the Isaac Regions,” Mr Webber said.

“From the diversity on show at Cape Hillsborough to the hiking experiences on offer at the Peak Range mountains, the Cosgrove chain provides tourists with both adventures and serene natural beauty.”

The Cosgrove volcanic chain extends southwards from Queensland, New South Wales and Victoria and its southernmost point is theorized to be located under the Bass Strait near the Northern Tasmanian Coast.
