“It’s a wild ride,” says Macdonald of the show.

“Helen is very much the grounding point of the series in my opinion.

The show was shot in the often testing environs of the actual Australian Outback.

“It was as tough a filming environment as I’ve ever been in.

The Outback is no joke.

We’re miles from proper civilization as we’ve come to know it.

But I think that’s galvanizing, I think that’s bonding.

I made brilliant friends with the whole crew as a result of those conditions and being out there together.

But, yeah, it wasn’t the easiest job I’ve ever done.”

Even the Australian Macdonald found the conditions in the Outback to be tough.

“So it’s very very different for me.

It’s really quite a magical place.

It really is such a magical place, but the elements definitely are a lot tougher.

There were sandstorms that would rage through quickly.

The flies are very real out there.”

So did Macdonald introduce her costar to any Aussie customs?

“He fell in love with Shapes, these little biscuits that we have,” she says.

“They’re not cookies, they’re savory.

So they’re kind of like crackers, I guess.
