Australia's Gallium Supply Chain is a national snapshot of the gallium sector as of January 2026 including production, resources and exploration.Gallium is a critical mineral which is exclusively produced as a by-product – primarily from bauxite processing and, to a lesser extent, from zinc residue processing. Growth in gallium demand is tied closely to its use in light emitting diodes (LEDs), integrated circuits, photovoltaics, neodymium-iron-boron (NdFeB) permanent magnets used in wind turbines and electric motors. More recently, gallium demand has increased due to its use in compound semiconductors, including gallium arsenide and gallium nitride conductors, which enable high‑frequency, high‑power and high-efficiency electronic devices, critical for telecommunications, defence and aerospace systems.
