Price of petrol + Big Mac + Bank interest rate in Australia November 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 November 2025 probably averaged $1.90 for unleaded 91 Octane. Add up to 15c for 95 or 25c for 98.  It’s relative of course due to fluctuation. The month started off at 1.86 and peaked at 2.27 on the last week for me. 

The price of diesel was around $1.90 the last time time looked and this the price does not fluctuate much compared to unleaded. Adblue was priced at about $1.90 per litre.

Following the developments during November in the US market regarding tariffs : It is becoming clear that the Tariff is yet another PR sunt that has gone wrong. Instead of other countries towing the line few have 

Tariffs and continual high inflation are no longer news worthy as Government shutdowns and other distractions take hold. The lack of any consistency on tariffs levels have also made it pointless, to be honest. The US appears to be losing its economic superpower status which is not good news.

The price of a Big Mac in November 2025 now averages $8.40. The price for the burger alone does vary from store to store based on location! This time it was the usual shopping centre location. The medium sized meal deal which included fries and a drink costs about $13.55 and the large option was $14.45 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 interest rate remained at 3.60 % 
The variable home loan interest rate range in November 2025 in Australia was : 4.5% – 9.5%
The saving interest rate range in November 2025 in Australia was : 0 – 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:
