In one year alone the amount of trash removed from Booderee National Park on the south coast fills three shipping containers, with the majority going directly to landfill.
Park rangers are gearing up for the summer holidays with more than 3000 people per day expected to take advantage of the beautiful beaches at the peak of the season.
However, with tourists comes trash, and the biggest problem, a park spokesman said, was visitors who "carelessly disregard their rubbish without due regard to its impact, or who is going to pick it up".
The Keep Booderee Beautiful campaign is addressing the issue head on, with a reminder for tourists and locals alike to love the area, but not to death.
"Unfortunately in the past few years there's been a noticeable increase in rubbish in our park, on our beaches and in our marine environment," the spokesman said.
In fact, more than 80 cubic tonnes of rubbish is removed from the park annually. About 90 per cent of that goes to landfill, the rest is recycled.
Booderee National Park manager Michelle Callaway said littering puts "massive strain" on park resources, and threatens birds, wildlife and the marine environment.
As part of the campaign park rangers will engage directly with visitors, providing them with tote bags, bumper stickers and a map of rubbish drop-off points in the park to help get them on board.
The campaign began on the first day of summer with a clean-up blitz at Iluka Beach, with HMAS Creswell staff, the Wreck Bay community, the local school and park staff helping out. Plenty of beer bottles and takeaway coffee cups were removed from the beach, as well as plastic bottles, soft drink cans and pieces of rope.
"The blitz will ensure visitors are greeted with a pristine environment, and set a standard for the holiday season," Ms Callaway said.
She said there was also a stick approach this season for those who had no regard for either their fellow visitors, the park's traditional owners or the wildlife.
"We'll be ramping up compliance activity on our park this summer. We'd rather not hand out fines, but we will if necessary."
Each year the NSW south coast accommodates hundreds of thousands of people who flee the city to relax and find their slice of paradise.
"People come to visit the park for its unspoilt natural beauty and we are appealing to all visitors to help us keep it that way."
Over a year, about 450,000 people visit Booderee National Park, which is just one of 35 national parks and reserves along the south coast from Wollongong to Eden.
Fairfax Media's Keep it Clean campaign will be running over the summer school holidays to remind readers to love holiday destinations, but not to death.
