IMAGINE never having to cook or do laundry and waking up somewhere new almost every day.
That's the life Yvonne and Russell Parry have enjoyed for a total of 4036 days of the past 15 years, making them Australia's biggest cruisers. 
After returning from a 35-day Hawaiian cruise yesterday, the couple (pictured) will today set sail again on the Sea Princess on a 104-day world cruise.
Geelong-based Mrs Parry said they were unashamedly addicted to the "thrilling" lifestyle cruising afforded them and would spend the rest of their lives at sea if they could.
"We really believe we have the best life. We want to live forever," said Mrs Parry, 69, who estimates they've cruised more than 150 times.
"We don't regret a single day. We think this is our time, when we can do what a lot of young people do - travel the world. It's just that we don't have to backpack!"The Parrys are certainly not alone, with more than a million Aussies taking a cruise last year, up 15 per cent on 2014.
