Four new water-bombing helicopters will boost Queensland's frontline fire defences this summer.
Two of the choppers can dump almost three tonnes of water in one hit.
The Bell 214B helicopters are also able to source water while hovering over dams.
The Rural Fire Service says the new water-bombing fleet will have a big impact at large-scale bushfires.
"These helicopters provide a better resource than we've had in previous years," said Assistant Commissioner Neil Gallant.
"A single helicopter has the water-bombing capacity of 2.6 tonnes, or 2,650 litres of water."
The choppers will cost the State Government $6.1 million for the next three years.
They will be especially important in south-east Queensland this fire season.
"We've had plenty of rain in the wet season thanks to (cyclone) Oswald, so there's a lot of vegetation out there," Mr Gallant said.
"A couple of weeks of those dry westerlies will certainly dry that vegetation out, and if we don't get anymore rain between now and December we're going to have significant fires."
The water bombing helicopters took to the skies over Ripley, west of Brisbane, for a training exercise today, with 30 firefighters learning how to coordinate firefighting from both the ground and the air.
John McDermott owns the fleet contracted to the Rural Fire Service and also flies the aircraft.
"We've got an air attack supervisor who guides us as to where the hot spots are, or where any spot fires develop," he said.
"Then we work out what we're going to do with the fire.
"It's all about controlling the fire to a position where it can be worked on from the ground as well."
The water-bombing helicopters will be based at Archerfield and have an initial response area of 120 kilometres.
