Have you more precise info/link ? All I can find is that it's comparable to 1893 and 1974 incidents.

All climate indicators of ENSO remain beyond La Niña thresholds. The tropical Pacific Ocean remains much cooler than average for this time of year, with temperatures below the surface up to 4 °C below normal in central and eastern parts (comparable to the La Niña event of 1988). Trade winds are stronger than average, while cloud patterns continue to show a typical La Niña signature with suppressed cloudiness in tropical areas near the dateline. The Southern Oscillation Index (SOI) value for December of +27 is the highest December SOI value on record, as well as being the highest value for any month since November 1973. http://www.bom.gov.au/climate/enso/

Ok, perhaps once in a millennium was an exaggeration, but this kind of weather is unlikely to happen again in my lifetime. Noting also there is still two months of the summer wet season left to run it's course.
