The NSW Resources Regulator was established on 1 July 2016 as a standalone work health and safety regulator for the state’s mines and petroleum sites. This includes open-cut and underground mines, petroleum sites, quarries and extractive operations, tourist mines, opal and other small scale mines, and mining exploration activities. Since being established, its functions have extended to compliance and enforcement activities in relation to the Mining Act 1992, with a key focus on mine rehabilitation.
