Brisbane flood caused by global warming policy?

From EU Referendum:

This rain depression was slowly moving south without losing intensity and flooded the Burnett river catchment to the extent Bundaberg city suffered serious flooding. Still the rain depression moved south with very heavy rain, with the north easterly air flow carrying the rain right into the Brisbane river catchment.

Thus, the Wivenhoe dam management had plenty of warning that this rain was on its way and had been so for weeks. Yet the policy of the Queensland Government was to keep the dams full because of their advice from the likes of Tim Flannery et al. This was that, because of global warming, Queensland was going to remain in drought.
