Price of petrol + Big Mac + Bank interest rate in Australia March 2025

Welcome to my updated 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 March 2025 averaged $1.66 for unleaded 91 Octane. Add up to 15c for 95 or 25c for 98. The price for petrol did not vary much during the month and is the lowest price for at least months.

The price of diesel was around $1.80  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.  

Following the developments in the US that has applied tariffs to everything that comes into the country things are uncertain in the long term as there is essentially no long term plan to achieve anything or is there? My analysis by the next posts. 

The price of a Big Mac in March 2025 averaged $7.55. The price for the burger alone does vary from store to store based on location! This time it was in the city and was lower priced than the usual shopping centre location. The medium sized meal deal which included fries and a drink costs $12.90 and the large option was $13.80 as per my monthly visit. As always this is not a fixed price as McDonald’s has a very active app and promotional pricing and freebie schedule.

The RBA – Reverse Bank of Australia the country’s central bank kept the basic rate at 4.10%
The home loan interest rate range in March 2025 in Australia was : 4.5 – 9.5%
The saving interest rate range in March 2025 in Australia was : 0 – 5.0%
Note that the rates I saw came with conditions or short term promotion periods – very naughty. 
Furthermore with the reduction of the RBA base rate last week will see changes very soon. 

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:
