1. You can usually only see the ethereal lights of the Aurora Australis from Antarctica and Tasmania, but last night it was also captured by photographers in NSW, Victoria, WA and New Zealand!
2. Photographer Lachlan Manley took these shots from a nature reserve south of Geelong in Victoria.
3. The fiery sky was reflected off a lake in Jindabyne, near the NSW snowy mountains.
4. This photo was snapped at Montara Winery, in Ararat, southeastern Victoria.
5. You could even watch the aurora slink across the sky from Sydney's northern beaches!
6. HOW IS THIS EVEN REAL? A stunning timelapse by David Finlay and Rudi Vavra at Kiama on the NSW south coast.

7. The heavenly light show is caused by electrically charged electrons and protons speeding down magnetic field lines and colliding with neutral atoms in the earth's atmosphere.
Lights of Austalis early this morning. Well worth getting up at 4am. #southernlights#aurora#earlymorning#australis
8. According to the Bureau of Meteorology, the collisions cause the atoms to emit light at different wavelengths, in a process known as fluorescence.
