Alice Springs couple holds final Halloween display after 16 ...

Jeanette and Peter Gurrie are transforming their Alice Springs home into a haunting Halloween display for the last time.

The couple has dedicated 16 years and thousands of dollars creating an experience for trick or treaters.

Mr Gurrie said he could not even begin to think of how much they had spent on animatronics for their displays.

"We've spent just over $10,000 just on this year alone for the giveaways," he said.

"I think the first year we started, we gave away 500 to 800 lolly bags."

Mr Gurrie said he was now giving away more than 4,500 lolly bags, icy poles or fruit cups.

For the Gurries, Halloween has always been more than just a fun celebration.

"It's been a big part of our life," Mr Gurrie said.

"It certainly helped Jeanette and myself out through some tough times.

"It gave us something to think about, a bit of a distraction and it got us through."

The Gurries plan to spend more time focusing on their Christmas display from next year.

But Mr Gurrie said he hoped people would have fond memories of their Halloween displays.

"It's something we can give back to the community," he said.

"This wouldn't be possible without the public."

The popularity of Halloween in Alice Springs has been credited to the large American population who worked at the Joint Defence Facility Pine Gap.

"They absolutely love a Halloween," Mr Gurrie said.

"We sold a lot of our big animated props to a lot of Americans and some of their comments were, 'It's a lifetime investment,'" he said.

The couple has sold around 70 per cent of their animatronics and displays but kept enough for this year.

"We've gone back on previous years and figured out what everyone didn't like," Mr Gurrie said.

"We're going with clowns again this year, just to scare the bejesus out of everyone."

He said 90 per cent of the decorations would be staying in Alice Springs for future families to enjoy.

"That puts a smile on our face too."
