How Many 'Hot' Days In A Calendar Year ?

NWS Melbourne uses 95 F/35 C as the threshold for adding the "hot" descriptor to the forecast. I would rather use daily mean temp if the data existed, but this is good enough.

Average number of days per year (2002-2023): 5.7 days

Record highest: 16 days in 2011
Record lowest: 0 days in 2008 and 2014

YTD: 11 days

We get 2.9 days over 30°C per year.

The AU Capital Cities +35c days since 2010.

The city I live in has never registered a temperature above 35C/95F

Ask and ye shall receive:
Nearly all the Capital cities have 'warmer' sites more representative of the population hub. 
Both Sydney and Melbourne show this re the 'hot' days ( +35c ) per annum.
In the interests of fairness I've done sites similar distances away from the official AWS for both Sydney and Melbourne.

There it is, conclusive hard copy proof that Melbourne really is Heathrow with a couple of hot days thrown in.

greysrigging could you do Renmark?

I have done Renmark, just haven't published it yet
Renmark Airport:
2024 = 35 ( so far )
2023 = 38
2022 = 26
2021 = 32
2020 = 32
2019 = 56
2018 = 59
2017 = 56
2016 = 50 
2015 = 58
2014 = 52
2013 = 48
2012 = 39
2011 = 27
2010 = 38
Total = 646 days or 43.6c days per year av.

110°F is the hot marker here, and we avg 19 days per year with highs that hot

Too many

I think 86F (30C) is a reasonable threshold to use. Miami Beach averages 125 days at 86 or above
