The ABC is reporting that Katy Gallagher is interested in why ACT petrol prices are as high as they are.
Averaging $1.39 per litre, Canberran petrol is more than 10 cents more expensive than that of Sydney.
Ms Gallagher has written into the ACCC (Australian Competition and Consumer Commission) asking them to look into anything that may contribute to the rising price of petrol in the ACT.
