It's populated by excited youngsters every day of the year.
This little magic wonderland is in Queensland, just across the border from my home state, New South Wales.
I pass it on one of my favourite walks.
But this is just one side of the coin at Cooly ...
Little girls practise being mummies.
And others slide into their own different little world ...
Sometimes not even a big yellow slippery slide can make things seem right.
It's hard to believe that just across the way from this land of children there is a picnic shed where happiness is altogether more fleeting.
Here on most evenings, just as the cold creeps into your bones, homeless people gather for a handout of food from a small army of generous volunteers.
In this place of seeming plenty there is an increasing number of people - men women and children - who are without a safe place to lie their heads at night.
The new government says it will redress this wrong, but in the mean time the suffering continues.
Here, this has been the coldest winter for many years.
Tonight, as shadows lengthen and I walk my walk there is a man arrived early at the picnic shed, bagging his spot.
This homeless man wears sad track pants and hoody with warm newish-looking lambskin boots, and wheels a battered suitcase on a luggage trolley.
He carries a large teddy bear - his only companion.
Remarkably, the picnic shed is less than one hundred metres from the children's slippery slide.
