Kayla Hayes kept asking to stay up a little longer over the Australian Defence Force's Northern Australian Exercise Area on 18 September 2016. The Royal Australian Navy photographer was snapping the Exercise KAKADU 2016 fleet from a Canadian Sea King helicopter in 'The most perfect conditions' she had ever seen–moody dark clouds and storms.

September is usually dry in the Top End of the Northern Territory, but it's not unusual for showers and thunderstorms to form under certain conditions. That day, moist air from the northeast and instability from a low pressure trough across the Top End fuelled storms and thunderstorms.
