Price of petrol + Big Mac + Bank interest rate in Australia September 2023

Welcome to my more detailed monthly report on key financial figures for Australia. I am doing this to keep historical notes through my life. These figures reported are what I see at the various places and an aggregate.

The price of petrol I paid during September 2023 averaged $2.20 for unleaded 91 Octane. Add up to 15c for 95 or 25c for 98. The price for petrol was stable at around 2.20 during the month.

The price of diesel was around $2.20. the last time time looked and this the price does not fluctuate much compared to unleaded. Adblue was also priced at about $2 per litre.  

The price of a Big Mac in August 2023 averaged $6.60. The price for the burger alone does vary from store to store based on location! The Large sized meal deal which included fries and a drink costs $13.35 as per my monthly visit. The price is a ‘reduction’ from last month as it was basically the same price for a Medium sized meal deal. As always this is not the fixed price as McDonald’s has a very active app and promotional pricing schedule. 

The average home loan interest rate in September 2023 in Australia was : 5.5 – 7.5%

The average saving interest rate in September 2023 in Australia was : 0 – 5.5%
Note that the rates I saw came with conditions or short term promotion periods – very naughty. 

Note that fuel prices also vary according to area, the level of competition and a whole heap of other factors like shopping discounts, wars, world wide economics and so forth, however unreasonable high prices (relative to crude oil prices) is greed. Also note that the Octane level I post here represents Australian measurement which is different from those in other countries eg. US.

Apart from the actual prices I paid at the servo the websites I use to research the crude oil pricing are:
