Holidaymakers will be able to stay on Rottnest for up to 16 weeks - at greatly reduced prices - as part of a radical change to attract winter tourists.
Under the plan, to be released within days, 20 refurbished units in the Bathurst area will be available for extended-stay visitors at 45 per cent less than the normal rate.
Ten discounted ferry fares will also be offered for the duration of the stay and preferential rates will apply for the island's barge to allow extended-stay visitors to bring over their own furniture and fittings.
Currently, holidaymakers can stay on Rottnest for a maximum four weeks. Under the new booking arrangements, the discounted rate will apply to holidaymakers who want to stay on the island from eight to 16 weeks from June 8 to September.
Tourism Minister Kim Hames said it would be the first time that holidaymakers had the option of staying on the island longer.
"Rottnest is spectacular during winter and is usually about 8C warmer than Perth," Dr Hames said. "This long-stay accommodation has been designed for people looking to do something different."
The 10 return-ticket ferry tickets will be $34.50 each, down from the usual $81.50. A laundry will be available for the exclusive use of extended-stay visitors and a linen-change and unit clean will be offered at $50 for the four-bed units or $65 for the six-bed.
Rottnest's occupancy rate is usually about 40 per cent during winter. Dr Hames said the rate needed to increase to justify plans to improve the tourist attractions.
Improvements to the camping grounds and the golf course were part of the strategy to increase winter patronage.
"I expect retirees, artists and people who just love Rottnest will embrace the opportunity to stay there longer," Dr Hames said. "And the discounted ferry tickets means they can return to the mainland or invite friends and family over to Rottnest."
Retired public relations manager Vic Jeffery, who stays at Rottnest with his wife each winter, said the new offer was a great initiative and one that they would consider.
"I think it's a great opportunity for those people who like to go over to Rottnest to relax, to fish or to paint," Mr Jeffery said.
"The island is such a beautiful and tranquil place.
"Last winter, the island was nearly deserted so it makes sense that the authorities look outside the square to attract more visitors."
