Prime Minister Scott Morrison has put the competition watchdog on notice over rising fuel prices.

The cost of petrol has been rising across the nation, with prices in Melbourne hitting a 10-year high last month, and Adelaide motorists forking out an average of $167.4 a litre as of Monday.

"I want some answers out of the ACCC. They're the cop on the beat, they're the ones we fund to go out there and monitor why prices are moving up and down and how they're timed," Mr Morrison told K Rock 95.5 on Monday.
