I am in great need of HISTORICAL TEMPERATURE DATA (since 1998) of Australia. I would appreciate if half-hourly data is available. I am about to consider one of the following regions into my research: New south wales (NSW), Southerna Australia (SA), Victoria (VIC), SNOWY and Queensland (QLD). I am not able to find the exact link or database for these regions. Temperatue data of any one of the regions (or all) mentioned above would be a great help for me. Thanks in advance.
