There are 25 locations in Australia with daily temperature data going back before 1890. This graph shows all 1,389,419 daily maximum temperature readings at those locations since 1876.
The actual waveform is a 120 year long cycle. The hottest year was 1902 and the second hottest was 2018. Australia was cold during the 1970s ice age scare, just like everywhere else.
The real graph looks nothing like the fake graph generated by BOM, which uses hundreds of fragmented stations with short term records homogenized together into a meaningless hodgepodge of politically useful nonsense.

The hottest year of 1902 was at the end of the worst drought in Australian History – The Federation Drought.
These are all the stations used in the analysis :
