It may be the season to be jolly, but north Queensland's stinger season also officially started this month, with a box jellyfish caught at Port Douglas on November 1.

Marine stingers are a major concern at beaches including Port Douglas' famed Four Mile during the summer months, leading Surf Lifesaving Queensland to urge swimmers to use stinger nets.

Steve Pollard, President of Port Douglas Surf Life Saving Club, said the Four Mile stinger net went in on Monday, November 4, just days after a local lifeguard caught a "quaddy" box jellyfish (Chiropsalmus Quadrumanu, the least lethal of the two major box jellyfish) in the drag net.

"I don't know what the [stinger] season will bring, we will just have to wait and see," Mr Pollard said. 

Surf Lifesaving Queensland Lifeguard Supervisor Jay March said an Irukandji jellyfish was caught off Low Isles recently, and some swimmers at Four Mile suffered minor stings from bluebottles this week.

Though stinger nets limit are designed to prevent swimmers coming into contact with large box jellyfish, they do not keep out Irukandji.

According to Australian Marine Stinger Advisory Service, box jellyfish deaths have dropped dramatically in North Queensland since their introduction in the 1980s, and compared to stinger season beaches in the Northern Territory, where nets aren't used.
