Have you checked those figures, or are you just reposting something that you saw on the internet without checking it’s accuracy?
Fuel excise in Australia is $0.496 per litre, and GST is 10%. I’ll leave you to do the maths, but the numbers in that image are wrong.
However, after checking the above (did I mention that it is wrong btw?), I wondered how it’d compare to an EV.
If I assume that the $67 purchases 33.5 lt of fuel, and it was used in a car averaging 10 lt/100km, that $67 would cover 335 km (but ymmv).
A biggish EV will use 20 kWh/100km, so about 67 kWh to cover 335 km. If you recharged it at home and have PV, you’d be forgoing the FiT of about $0.11 per kWh. So it’d effectively cost you $7.37. If you don’t have PV, you’d be paying about $0.30 per kWh, or about $20.10
But here is the kicker… if you can recharge at home using your own PV, that (forgone) $7.37 is GST and tax free. So, instead of having to earn $100 to cover that 335 km, you simply forgo $7.37 in FiT credits. And as
@Paul Smedley has posted, sometimes it is even possible (in SA at least) to get paid to use that electricity, so even cheaper again.
