When I pulled into Wilpena Pound Resort in the Flinders Ranges today, I did not expect to have a financial awakening at the fuel pump. But that is exactly what happened.
Diesel here was $2.98 a litre. One litre of milk in the resort shop was $3.00. I stood there for a moment and genuinely could not decide which was more absurd.
Now, I could not run the Pajero on milk, so the diesel price was the one that mattered. And that is where the calculation started.
The nearest town, Hawker, is 54 kilometres away. I had filled up there on the way through and paid $2.45 a litre. That is a 53-cent-per-litre difference, which does not sound enormous until you need 100 litres. At Wilpena, 100 litres costs $298. At Hawker, it is $245. That is a $53 saving.
But here is the twist in this diesel price comparison. Driving to Hawker and back is a 108-kilometre round trip. At current fuel consumption, that burns roughly $22 worth of diesel. So the net saving from driving to the cheaper fuel is around $31.
That is not a small amount. And the calculation took me about ninety seconds to do in my head.
Most people skip this kind of thinking because it feels fiddly. But when you start running these numbers on your everyday spending, the results have a way of adding up fast.
So why does diesel price comparison matter beyond the obvious? Because it trains a habit. When you start asking ‘is the cheaper option actually cheaper once I factor in the real cost of getting it,’ you start applying that same logic everywhere. Subscriptions. Tools. Memberships. Services you signed up for and forgot about.
I have been on a personal austerity kick lately. Not in a painful, deprive-yourself way. More of a quiet audit. Going through what is leaving my account each month and asking whether I am actually using it and whether it is worth what I am paying.
When I did this recently, I found subscriptions I had forgotten entirely. I found one I was about to cancel before I noticed it was actually a lifetime purchase. Cancelling it would have achieved nothing except removing access to something I already owned outright.
I also found tools I had paid for and stopped using. Not because they stopped being useful, but because I got distracted and drifted away from them. Rediscovering those was actually more valuable than finding the forgotten subscriptions, because the tools were still good.
The diesel price comparison at Wilpena Pound is a simple example of something that applies far beyond the fuel pump. Before you pay the higher price for convenience, spend ninety seconds running the numbers. Before you cancel a subscription, check whether you own it outright. Before you buy a new tool, check whether you already have one sitting unused in your account.
Small financial decisions done with a bit of deliberate thinking will save you more across a year than most people realise. Not because each decision is massive, but because they compound.
