A quarter of a million mock power bills attacking the Barnett Government's power price increases are being dropped into letter boxes in marginal seats across the State.
The flyers are the latest tactic in the State Opposition's push to highlight cost of living pressures ahead of next year's election.
The flyers claim power prices have gone up by 62 per cent.
Shadow Treasurer Ben Wyatt told the ABC the price rises under the Barnett Government have been unreasonable.
But he was unable to detail how householders will fare under a Labor Government.
"I can certainly say that the policy will be much more considerate to Western Australian families to ensure that we don't get these sort of rapid increases that we've seen over the last four years," he said.
The Energy Minister Peter Collier says that Labor can not take the higher ground when it comes to power price rises.
"Their logic with regards to this argument is completely without foundation," he said.
"It's like having a sky-scraper without any foundations.
It's just going to come crumbling down.
"Now quite frankly, the Opposition have absolutely no credibility when it comes to electricity price increases."
