Some of this country's most spectacular weather phenomena are captured and explained in the Bureau of Meteorology's 2020 calendar, with the theme 'Weather safety for all Australians'.
BoM chief executive officer Dr Andrew Johnson said competition for inclusion in this year's edition was as tough as ever, with hundreds of amateur and professional photographers submitting their snaps and a final 13 pictures going into print.
"I am proud to say that our 2020 calendar includes images from every state and territory, as well as Antarctica, so we're covering Australia and beyond, from the tropics to the frozen continent," Dr Johnson said.
"It features everything from fascinating cloud formations, such as the incredible morning glory cloud above Burketown in north-west Queensland, to an intricate close-up of a frosted leaf near Canberra.
"Every page provides an insight into both the striking visuals and the danger posed by severe weather conditions, so it perfectly fits our weather safety message of 'Know your weather. Know your risk'."
While Martin Ascher has always had a love for photography, it's his passion for the local community that gives him the motivation to capture his hometown of Mallacoota through the lens.
Having helped set up the Mallacoota Fundraising Group a few years ago, Mr Ascher now donates his images for a calendar that sees all proceeds go back to emergency services in the community.
"All of the emergency services here are voluntary, so we're very proud we've been able to make a contribution and support the people of Mallacoota," he said.
"Here where we live, you can just about point the camera in any direction, and you'll get a beautiful picture.
"I just love the remoteness, it's unspoiled; you can walk all day and you won't pass a single person."
On this particular day, he said he got up early and noticed the colour in the sky, taking off before daybreak to photograph the scene.
"There'd been bushfires in the area and it created the most spectacular sunrise, and to get the reflection off the water as well was just amazing," he said.
You can see Mr Ascher's photo, along with the other breathtaking pictures, in the Australian Weather Calendar 2020 at www.bom.gov.au/calendar.
