Ask most parents of young children and they will tell you the mention of bottoms, poo or farts incites fits of incomprehensible giggles among their offspring.

So it is no surprise that remote outback toilets have captured the imaginations of Quinn Huber, 10, and his brother Theo, 9, during a trip around Australia.

The boys, from Lansdowne near Taree in New South Wales, have spent the past six months travelling with their parents Meg Norling and Florian Huber, hauling a camper trailer named Rondi.

The family travelled clockwise from their hometown, through South Australia, across the Nullarbor, into the Kimberley and down the centre.

The trip encouraged the boys in their outdoor play as they explored creeks, chased tumbleweed, rode their bikes in the dust and discovered new tactile sensations.

Their adventure ticks all the boxes in a movement encouraging Australia's kids to step away from their screens and get outdoors and dirty, with research showing the wide variety of benefits to children's minds and bodies.

Along the way, they have seen waterholes, hot springs, road trains, Aboriginal art, caves — and toilets of every variety, documented by the boys in their Daily Bog Blog.

Unearthing the best rural pit-stops

But why toilets, when there is so much else to captivate the minds of two energetic and imaginative children?

"Well, you use them several times a day; you're on the road and they're the only structure around," Theo explained.

"The first time, when we get to places, we go over to the toilets and check them out."

Trying to pin the boys down to name their favourites is difficult because they have so much to say about each of them.

Among the best 'bogs' were those they dug themselves, excavating the deep red soil with their spades and adding toilet roll holders made of twigs.

"One time I dug up someone else's and that's the worst thing," Quinn recalled with a squeal.

The toilet known as Camelot, at Sceale Bay in SA, was a stone-built long drop with a window facing the sea, where the boys were treated to the sight of dolphins backflipping in the waves.

Another memorable loo was the Concrete Crappa in Minnipa, South Australia, while the long drop on Kangaroo Island caused some consternation.

"One on Kangaroo Island had bees down it and we were scared bees would bite our bums," the boys chimed in unison.

In fact, "stinky, fly-filled" long drops were the stuff of nightmares, with both boys fearful of a rear-end attack by crocodiles or a cane toad.

'Scary' automatic toilets

But what terrified Quinn and Theo the most were the dreaded Exeloo automated self-cleaning toilets at Katherine in the Northern Territory, and Halls Creek in Western Australia.

"The scary thing is, you walk into there and the door closes and you think you're being spied on and they play music," Theo said with a shudder.

While neither had seen snakes or redbacks, they reported several dead bats and quite a lot of other spiders.

Animal lover Quinn also tried to save a green frog on the lip of one flushing toilet.

"I put my hand in the bowl to splash it with water; I love frogs," Quinn said, as his mother recoiled.

Unlocking new worlds

Ms Norling said she had always planned to take her sons travelling before they reached high school or "didn't want to hang out with us anymore".

She said they had met a few families travelling with their children, usually for three to six months at a time, and one family who had been on the road three years.

"Six months is nothing in their little lives, and a few things have happened on the trip," she said.

"They're really into their books, which is a side effect I wasn't expecting, and their relationship has strengthened.

"Quinn has loved all the different insects that he's found and taken photos of, and Theo has named every variety of car along the way."

Ms Norling said the boys were being schooled via distance education and received satchels in the mail every two to four weeks containing their teaching resources.

With Quinn in Year 5 and Theo in Year 3, the family arranged to spend a few days in Albany, Western Australia, to do Naplan — with both boys doing "really well" in the test.

The boys have just arrived home and thanks to their 'hands-on' research, have designed what they consider to be the perfect toilet.

It is named 'Sat On' and the logo features a toilet seat for the 'O'.

With innovators like this, it seems the future of camping ablutions in Australia is in good hands.
