Munibung Hill is an example of the youngest Permian geological series, 251 millions years ago, before the Triassic terrestrial sediments dominate 199 millions year ago.
Munibung Hill has some of the youngest rocks of the Newcastle Coal Measures. These rocks formed during the Permian period around 250 MYA, when tectonic plates were colliding and subducting along the eastern side of Australia. This resulted in a series volcanoes and high mountains in the New England region to the north. Rain and snow-melt flowed southward from the mountain peaks toward the ocean and carried gravel, sand, mud and large volumes of volcanic ash. A complex network of channels formed levees, with associated lakes and swamps.
Lake Macquarie was formed following the Pleistecene glaciation 2.6 million years ago and lasted until about 11,600 years ago.
Sea levels only stabilised about 6,000 years ago.
