Don't forget to factor in the various Govt taxes and excises.
A litre of imported petrol at 5c litre will cost the same as a 50c litre for transporting it into the country and distributing it.
Our oil and fuel prices will never reflect the base cost per barrel, unless we are self sufficient in drilling for it, refining it and eliminating Govt taxes.
From what i've read, the crude oil price accounts for 90% of the cost of producing a refined fuel. That'd leave the rest being refining, distribution and tax costs, bla bla bla..
As such, crude oil price gives a good indicator as to the retail price movements we as consumers should see (taxes included). If crude price drops 70%, as has been the case, there should be a proportionate drop in the retail price. Unsurprisingly, the retail price is slow to react to a downward crude price trend but lightning fast on the upswing. Sadly we've yet to see anything close to a proportionate drop in this cycle regardless of any expected lag.
Simply put, there is profiteering and a lack of competition that is occuring which the government wont address the issue. As is, the government has hude cost issues to worry about NOW due to the COVID19 spend but even in better times they've chosen to ignore fuel pricing becasue they benefit from it via their high taxes.
At the end of the day, look at the graph
"Figure 1" in this government report (i haven't read the report myself but the graph is telling).
According to the graph in this government report, when WTI crude was at $100AUD/barrel the retail price opetrol in Sydeny was at $0.60/litre*. Let that sink in for a bit... And taxes haven't appreciably changed since 2003.
Given WTI crude is almost always cheaper than TAPIS crude i quoted in my post above, but ignoring that fact, TAPIS is currently @ $47AUD/barrel, the graph should give some clear indicatins as to pricing now. So what price should we be paying for unleaded in 2020 when TAPIS is @ &47/barrel? maybe $0.30/ltr*? ... not the currently asked for $1.30 odd (give or take the 20c +/- swings).
There is a lot more gouging going on that what people realise and it can't be factored by taxes and distribution costs... Time for people to wake up...
* i remember petrol prices were around 80-90c/l and in some cases almost $1/l in early 2003 when i took a drive along the hlaf of the eastern seaboard. in that context current prices could be as high as $0.50/l
