The explosive environmental issue of the early 1980s was the campaign to protect the Franklin River, one of the last wild rivers in Australia. ACF mobilised supporters and resources behind the campaign that went all the way to the High Court to prevent the damming of the river. A pervasive theme in the 1980s was the fight for Australia's native forests. In 1987, ACF and other environment groups pushed forests into the spotlight. Daintree's tropical rainforests finally gained World Heritage listing in 1988, despite the vehement opposition of the then Queensland Government. Kakadu's cultural and natural qualities were again under threat from uranium mining during the 1980s.
