Imagine you're in charge of an open-plain zoo.
You're about to receive some very special charges, chimpanzees. These ridiculously cute little babes are known for their intelligence and cheek – and for being able to short-circuit electric fences.
How do you keep them from escaping into the Australian bush?

It was one of the more challenging projects faced by Monarto Zoo's Director of Life Sciences, Peter Clark, who has reflected on its success as the zoo prepares to throw its 30th birthday party this weekend.
The hard work put in by staff paid off a little over 12 months ago when the zoo welcomed its first baby chimp.
"I'm not big on birthdays but this one is important .... I'm only 10 years into my time here but a lot has happened," he said.
"When it started, Monarto was basically a bus tour. We changed that five or six ago when we set up a series of bus stops so people could get off the bus and go and do what they wanted to do – like feed a giraffe or pat a rhino."
Spanning 1,000 hectares of mallee country, in 30 years Monarto has transformed from a closed breeding area to an interactive African safari experience for tourists.
Breeding and conservation remains at its core and its successes are celebrated over and over such as its success with bringing Przewalski's horses back from the brink of extinction.

In the 1960s, the species was extinct in the wild in its native Mongolia. However, in 1995, Monarto released seven horses back into the wild and in 2005, the wild herd number was 1,500. They are still bred at the zoo today.
"A lot of people can't afford to go to Africa," Mr Clark said.
"Our next step is accommodation to give people a real safari experience."
