The video above shows a Aircrane helicopter scooping water and then dropping on a wildfire north of Sydney, New South Wales. As the aircraft flew over the ocean it lowered a pipe into the water with a scoop on the end, forcing about 2,500 gallons into its tank.
Below we see infrared video of the fire shot from a NSW Rural Fire Service aircraft, apparently in the early stages when the blaze was much smaller.

The Australian Bureau of Meteorology is predicting that the eastern half of their country will experience a summer that is warmer and dryer than normal. That season is just beginning; their highest temperatures usually occur in January and February, but Tuesday produced the hottest December day in Sydney in the last 11 years, hitting 39.2C (102.5F) at Sydney Airport.
Below is an excerpt from an article at Australia’s ABC News about how Tuesday’s weather could affect wildfires:
Fire danger warnings are in place across a large part of Australia, with hot temperatures and windy weather expected, the Bureau of Meteorology (BOM) says. Fire authorities are on alert in the south-eastern states, with total fire bans in place in regions of South Australia, New South Wales and Victoria, and a high danger in Tasmania.
Temperatures were forecast to reach the mid-30s in the southern states, with a maximum of 36C in Sydney and Adelaide, 34C in Melbourne and 33C in Canberra.
In Darwin, the maximum expected temperature was 34C, 29C in Hobart. Perth’s forecast top was a cooler 26C and Brisbane 29C.
High temperatures in several capital cities at the same time is “a bit different”, senior BOM meteorologist Claire Yeo said.
“Those hot temperatures ahead of that wind change [are] increasing the fire dangers into that very, very high to severe range,” Ms Yeo said
“But there is also an added impact that we don’t necessarily or aren’t necessarily able to reflect in the fire danger rating, and that’s the way the atmosphere behaves in these kinds of conditions.
“Today is a classic example where if a fire was to start in your particular area, the atmosphere is primed for [it]. If a smoke plume develops over that fire, it can get to quite an extensive height … and we see very erratic fire conditions and fire behaviour in that kind of atmospheric condition.”
Ms Yeo said more frequent fire danger ratings were expected in coming days.

Above: the Aurora national bushfire prediction, detection, simulation and early warning system.
Researchers in Australia are designing a wildfire modeling system that firefighters can access on a portable device in the field even if they are not connected to the internet. The Australis Wildfire Simulator is intended to be part of Aurora, a national fire prediction, detection, simulation and early warning system that simulates bushfires in real time and rapidly communicates the spread predictions via the web, email and the National Telephone Early Warning System (NTEWS).
Researchers at The University of Western Australia are developing the new touchscreen device that can be mounted in a fire truck to help firefighters predict where and when a bushfire will spread.
The researchers are modifying bushfire simulation software Australis into a high-end tablet to provide accurate predictions of fire behaviour more rapidly than current methods.
Professor George Milne from UWA’s School of Computer Science and Software Engineering said the technology could protect lives, homes, crops and livestock in Western Australia’s bushfire prone areas.
“Having the Australis fire prediction technology in the cab of a fire truck or a farmer’s ute will enable first-responders to get the best information necessary to create appropriate firefighting and evacuation strategies,” Professor Milne said.
“This can happen in the very early stages of a bushfire, when time-critical responses are required.”
Professor Milne said the touchscreen device would complement the Aurora system used by the Department of Fire and Emergency Services (DFES) which currently runs the simulator from one central location for all fires in WA.
“On a day where there are several bushfires across the state, it may take too long to predict each individual fire’s progress using a single system in the central headquarters,” Professor Milne said.
“The advantage to local brigades with access to this technology is that it will give them location-specific information about which communities are at risk and which need to be evacuated.”
The Australis system analyses data including geographical topography, vegetation types, WA bushfire prone hotspots, time since last burn, rate of spread, fuel accumulation and forecasted weather.
In a matter of minutes, and without internet connectivity, it can accurately predict where the fire could be from 30 minutes to 24 hours into the future.
Professor Milne said WA is unique in the world; it has bushfires burning every day of the year, from the north during the winter dry to the south in summer.
“This technology could significantly minimise the impact of bushfires, the loss of lives and homes, by predicting the direction, intensity and rate of bushfire spread in real time,” he said.
Funding is still required to get the technology off the ground and made available to local bushfire brigades.
Along with DFES, Department of Parks and Wildlife and Landgate, the University of Western Australia has an application for Royalty for Regions funding under consideration by the WA State Government.
A NASA satellite captured an unusual smoke column over a bushfire in Western Australia December 8 southwest of Walpole. Apparently there was little wind to disperse the smoke, causing it to build up in a round shape, as seen overhead. This was very different from the smoke pattern we showed you on December 7 created by another fire in Western Australia.
The red dots are heat detected by the visible Infrared Imaging Radiometer Suite (VIIRS) on the Suomi NPP satellite.

A large bushfire in Western Australia forced authorities to close a major highway resulting in hundreds of long-haul truckers and tourists being stuck on the road for hours. Some of them were stranded between roadblocks that were 170 kilometers (105 miles) apart.
Wednesday morning the Eyre Highway across the Nullarbor was closed between Caiguna Roadhouse and Madura. By evening it was open again.
There were two large fires south of the highway that were being pushed by the wind toward the road.
The fire started from lightning four days ago 20 kilometres (12 miles) south of Cocklebiddy.
Below is a time-lapse video of satellite photos of smoke from fires in the area.
This time-lapse video of the pyrocumulus cloud over the Sedgerly Fire in Queensland, Australia is fascinating. According to the description by the Bushfire Convective Plume Experiment it shows a thunderstorm initiated by the fire. If you look closely you will see rain and lightning.
