If you have to travel that far and cant fit them all into your car fridge, dont make the mistake of putting them into an esky with ice, as the ice will defrost the prawns.
Just wrap them up to keep the direct sun off them and leave them in the boxes.We have people drive up from Katherine 300kms away and drive back and they are still frozen.. These will be at about -25 so they are far colder than ice which is about -2.
