$200 AUD a litre? There’s no way that’s real

Cents
Ok, that makes cents.
There are no units on that website and I’ve only seen gas stations list prices in the dollars-and-cents format ($5.99 instead of 599¢).
Looking at it a bit closer, you’re paying $1.79AUD/litre.
To compare to the U.S. (where the OP’s signpost is clipped from in the meme), $1.00AUD trades for $0.72USD as of this writing, so $1.79AUD would be $1.29USD. Then, to get from litres to gallons, we see that there are ~3.79 litres in a gallon. Multiply $1.29 by 3.79 and you get 4.8891, or $4.89USD per gallon, which is about on track with what we are paying here in some states, maybe a little less. I am open to correction on this math.
