While this drought has been intense and sustained, the millennium drought of 1997-2005 is still considered to have been the most devastating affecting nearly 50% of Australias agricultural land.
With no feed, farmers have been forced to ship in grain or hay from other parts of the country to keep sheep and cattle alive, spending thousands of extra dollars a week just to stay afloat.
The brown surrounds at the O'Brien farm echoes the experience of many other NSW farmers.
The drought has hit farmers particularly hard, with crop, water, and fodder shortages putting their livelihoods at risk. So wild animals were not deprived of water the cattle, the government of New South Wales has taken such a step.
"Many farmers are taking livestock off their paddocks, only to then see kangaroos move in and take whatever is left - this is the last thing any farmer needs at the moment", Blair said.
The state government also lifted the number of kangaroos that farmers are allowed to shoot and reduced bureaucratic red tape facing land holders applying for permission to shoot.
The government would have been better off subsidizing professional shooters to reduce kangaroo numbers more humanely, he said.
"This is probably the worst possible outcome for the kangaroo, but we do understand the plight farmers are in", Mr Borda added.
"Australia's rainfall varies greatly from one year to the next and from one decade to the next, and is strongly influenced by large scale phenomena such as El Niño and La Niña", Australia's Department of the Environment and Energy says on its website.
The Bureau of Meteorology's latest climate outlook for the next three months is predicting high chances of warmer and drier conditions over the drought-affected regions.
Though Australia has long suffered from spells of drought, other parts of the world are now experiencing extreme weather which experts say is evidence of the Earth's changing climate.
