In 1995, the Australian Bureau of Meteorology showed these temperature records:
New South Wales Bourke 52.8C January 17, 1877
Victoria Mildura 50.8C January 1, 1906
Queensland Cloncurry 53.1C January 16, 1889
Western Australia Eucla 50.7C January 22, 1906
All of those records have since been erased by the Bureau of Meteorology, as have all temperatures prior to 1910.

The temperature record at Mildura is visible in the NOAA GHCN daily temperature database. All of the hottest weather there occurred before 1910.
On January 6, 1906 Mildura, Victoria reached 124F (51.1C) and on January 5 reached 123F – one year after reaching 122,5F.

Over the past 150 years, Bourke has had 3,319 days over 40C, of which 2,393 occurred more than fifty years ago.
Unfortunately though, all of the data from January 1877 is missing so I can’t see the 52.8C record on January 17, 1877.
That occurred during a record El Nino and AMO which led to the deaths of tens of millions of people.

In the 2000 version of NASA global temperatures they showed 1878 as the warmest year prior to 1980, but then they altered the data to make the prior warmth disappear.
Alice Springs also had their hottest weather prior to the year 1910.
