After two years of heavy rain and record floods across eastern states, La Nina is finally over but authorities warn more extreme weather could be on the way in the form of a drought.
The Bureau of Meteorology issued an El Nino watch on Tuesday, after long-range forecasts revealed a 50 per cent chance of the warmer, drier weather pattern occurring this year.
More neutral weather is expected throughout autumn and winter, while hotter conditions could occur by summer, the Bureau of Meteorology's Andrew Watkins said.
