Have you ever wondered what lava looks like when it cools down? This short video introduces rocks from volcanoes and their features using some of the samples in the Geoscience Australia Education Centre. Viewers are shown different types of lava rock, bombs, obsidian and pumice. The video is suitable for middle primary and older students as well as a general audience; it introduces some technical terms and uses samples available for school students to handle during visits to the Centre.

This report presents key results from the Upper Burdekin Groundwater Project conducted as part of Exploring for the Future (EFTF)—an eight year Australian Government funded geoscience data and information acquisition program. The first four years of the Program (2016–20) aimed to better understand the potential mineral, energy and groundwater resources in northern Australia. The Upper Burdekin Groundwater Project focused on the McBride Basalt Province (MBP) and Nulla Basalt Province (NBP) in the Upper Burdekin region of North Queensland. It was undertaken as a collaborative study between Geoscience Australia and the Queensland Government. This document reports the key findings of the project, as a synthesis of the hydrogeological investigation project and includes maps and figures to display the results.
