In 2012, NASA published famous 'Black Marble' night lights images. What are the lights in the uninhabited regions of western Australia caused by?

large cities
wildfires
oil drills
open-pit mines
These images were as­sem­bled from data acquired over nine days in April 2012 and 13 days in October 2012. This means fires and other lighting (such as ships) could have been detected on any one day and in­te­grat­ed into the com­pos­ite picture, despite being tem­po­rary phe­nom­e­na - giving the the ap­pear­ance of a massive blaze.
