At the boundary between the basalts of the western suburbs of Melbourne and the Silurian sedimentary rocks of the eastern suburbs, the Merri Creek meets the Yarra River. The location is rich in the history of contact between Indigenous and European peoples, and in the industrial history of Melbourne. It holds the complex geological story of the lavas and turbidities that underpin the geography of Melbourne, told by Dr James Driscoll and Mr Rob Gell AM.
Australia’s caves were formed over millions of years, and exploring them is a journey to a hidden underworld that holds many wonders. But caves and karst landforms need our protection. They house complex ecosystems, critical habitat for plants, animals, and micro-organisms which, in many cases, cannot survive elsewhere. The biggest threat is overuse from tourism – which builds positive awareness, but also damages their natural integrity.
Bernie was a geologist and geomorphologist specialising in landslides and volcanism, especially in the Newer Volcanics Province of Western Victoria, where he worked to map the regolith landforms that tell the story of Victoria’s past while determining future volcanic risk. He applied his expertise to the neotectonics of South-Eastern Australia, the recently-active and active volcanoes of the Pacific region, and the morphotectonics of the Central Victorian Highlands.
Our sea levels are rising. Understanding the dynamics of the beach envelope and its overlap with human infrastructure is fundamental for effective coastal management. Dr David Kennedy studies the dynamic adaptation of beaches in the past to inform how we can manage them into the future. While NSW beaches have been studied for decades, but we are only just starting to understand the behaviours of Victoria’s beaches and their underlying geology.
