Kalgoorlie has narrowly beaten four Pilbara mining towns to claim the unenviable title as the most expensive West Australian destination to fly to.
Statistics released by the Pilbara Regional Council for the week to January 20 show the average Qantas return fare to the Goldfields town cost $606, or $0.55 per kilometre of travel.
The figure is more than three times the cost to travel from Perth to Melbourne at $0.16 per kilometre while a return Perth to London flight cost $0.07 per kilometre.
Newman [$0.39], Paraburdoo [$0.38], Port Hedland [$0.36] and Karratha [$0.29] rounded out the top five most expensive WA Qantas flights per kilometre, according to the PRC statistics.
The weekly figures are part of a campaign aimed at lobbying airlines to reduce the cost of travelling to mining regions in WA.
City of Kalgoorlie-Boulder Mayor John Bowler said the cost of flying to and from Kalgoorlie had been an ongoing issue for residents, with flights to Bali - five times the distance from Perth - being cheaper.
"When I was a member of Parliament it was a constant complaint," he said.
"Every three or four years, I would go and meet with Qantas and SkyWest officials and they would say well there's competition, there's two airlines [flying to Kalgoorlie].
"I feel a bit like the average Australian shopper who knows due to the very strong duopoly of Woolworths and Coles they may be paying more than they should.
"If there was stronger more even competition then the prices would be lower, I feel that, I think most Goldfield residents feel that."
Qantas and Skywest operate daily flights from the regional airport which services about 30,000 Kalgoorlie residents.
Member for Kalgoorlie Wendy Duncan said the region's mining downturn may have triggered the expensive flights.
"I think we've seen a downturn in mining so a lot of the flights aren't as fully occupied as they have been in previous years so perhaps the high cost is an indication of reduced usage," she said.
"When you think the price of fuel has dropped quite dramatically in recent times, I think we really shouldn't be seeing the cost of our flights increasing.
"The per kilometre cost really shouldn't change from one destination to another, the cost of flying an aircraft is the cost of flying an aircraft."
A Qantas spokesman said the airline determined its fare prices based on the level of demand between two destinations, not kilometres travelled.
"Qantas has been serving regional communities for a very long time and we understand the frustration when regional airfares appear to cost more than airfares between major cities," he said.
"A key factor of airline economics is scale, and it's generally more expensive for an airline to operate a smaller aircraft on shorter flights than larger aircraft on longer flights.
"This is the same for all airlines across the world, and it's because larger aircraft are generally more efficient to operate and can obviously seat more people.
"It's worth noting that we are regularly on sale in regional WA and that 75 per cent of our customers in regional WA purchase our red e-deal fares."
