'Mining state': resources flex fights One Nation surge

Key points

• NSW's Natural Resources Minister Courtney Houssos used a mining expo to promote the state as open for business. Polling commissioned by Advent Energy shows Labor and One Nation tied on 33 per cent of voting intention in mining heartlands.
• Premier Chris Minns said One Nation's leaders were polling well, but stressed that no one had voted yet. Both One Nation and the federal coalition criticised NSW Labor after a High Court decision blocked a Hunter mine expansion.
• Minns announced a one-off intervention to protect at least 400 jobs.
