More people can register to witness this year's turtle hatchling program in Darwin.
Parks and Wildlife says the popular program at Casuarina Coastal Reserve has vacancies on its waiting list.
Marine wildlife officer Ray Chatto says he expects at least three clutches of about 50 baby flatback turtles to hatch and head to the water over the next few weeks.
"Ring in and get on the list, and hopefully you'll get a turn this year," he said.
"If not, you'll be next cab off the rank for next season."
Flatback turtles, which breed only in Australia, are classified as a threatened species.
