During last year's Earth Hour Mr Robinson, the manager of Halifax Holiday Park, hosted a movie night that resulted in a 60 per cent reduction in power use for the hour.

This year, Port Stephens Council's four holiday parks and beach resort are participating in a friendly challenge to see which one can save the most power during Earth Hour.

Mr Robinson plans to build on last year's achievement.

"We want people to turn off non-essential appliances, come to the centre of the park and join us for something to eat and watch a movie," Mr Robinson said.

"It's about more than going around and turning circuit breakers off, it's about community involvement."

It follows a host of initiatives that Mr Robinson has introduced as part of the park's environmental management plan.

They include installing solar lighting and energy-efficient light bulbs and converting the amenities blocks from electric to gas hot water systems.

"In January and February this year we had a 30 per cent reduction in electricity compared to the last three years," Mr Robinson said.

In addition to energy conservation, the park is in the process of restoring as much of the area's indigenous flora and fauna as possible.

The park has also been awarded a silver gumnut award. The industry awards recognise a demonstrated commitment to environmental sustainability.

"Because the park is run by Port Stephens Council I feel that we have to lead by example and it's working really well," Mr Robinson said.

"We are definitely getting results and saving money."
