This is the second straight year of major flooding. It comes after the governments appointed so-called climate experts had projected increased semi--permanent drought was the problem to prepare for not flooding. See their report:
Excerpt from FUTURE DROUGHTS AND IMPLICATIONS FOR GOVERNMENTS
Global warming is a reality that is with us today. We can expect that the impact of drought in Australia will get worse as global warming accelerates. CSIRO (2001) has projected increases in Australian temperatures of between 1C and 6C by 2070, much greater than the increases over the last 50 years. These temperature increases would lead to even greater evaporation and water stress during future droughts, much worse than in 2002. CSIRO (2001) has projected up to a 45% decrease in stream flow in the Murray-Darling Basin by 2070. Climate models have projected a marked increase in the frequency of extreme droughts under global warming conditions (IPCC, 2001). From WWF report authored by alarmist professor Karoly.
