Australia's favourite beaches are at risk of disappearing into the sea as global warming drives sea levels ever higher, prompting a betting agency to start offering odds on which strips are likely to vanish first.

Palm Cove in far north Queensland is 4-to-1 favourite to be the first to go, with Noosa and Byron Bay beach not far behind with odds at $7.50, according to online bookmaker Sportsbet.

Surfer's Paradise is also high on the list of beaches most likely to disappear, with odds at $11, while other surfing spots at Manly and Bondi in Sydney and Bells Beach on the Victorian coast are attracting odds at $21.

Melbourne's bayside beaches at Brighton and St Kilda round out the list at $26 and $34, respectively.
