Hundreds of NSW petrol stations slash prices after fuel excise halved

Hundreds of petrol stations across New South Wales and the ACT have already slashed their prices after the federal government halved the fuel excise.

It has been a week since the federal government halved the fuel excise to ease financial pressure on families after petrol prices skyrocketed earlier this year.

9News can reveal 227 petrol stations have cut their prices by at least 30 cents a litre over the past seven days.

But figures show large discrepancies between service stations with some motorists missing out on the savings.

At least 127 petrol stations, mostly in regional parts of the state, have not changed their prices yet.

In some cases, prices have actually gone up.

"It's really important as consumers that we reward the stations that are doing the right thing and that we drive straight past the ones that are doing the wrong thing, maybe even report them to the ACCC," Joel Gibson from One Big Switch said.

Meanwhile, the Ampol Foodary in Marsden Park decreased by 44 cents and the BP and Caltex Woolworths in Bonnyrigg fell by 43 cents.

The cheapest petrol as of midday was the Metro Guildford where E10 sat at $1.52 a litre.
