The six-part series concluded on Sunday night with rave reviews on social media and calls for a second series from fans.

But one of the producers of the series, David Taylor, said a decision on the series' future could be a while away.

"We're hopeful of a second series but we'll have to wait and see," he said.

"The discussion is to be had with the ABC… we'll be having a chat and we'll see if we get there."

If a second series does get off the ground, Taylor said he and the rest of the team at production company Playmaker would love to shoot in Canberra again.

"To my knowledge it was the first one-hour drama set and shot in Canberra," he said.

"We're amazed at how many people have said how great Canberra looked on screen."

Although Taylor admits there were some challenges filming in the national capital compared to Sydney or Melbourne, he said with ScreenACT's support the producers were able to film everything they dreamt of shooting.

"We had a fantastic experience with Screen ACT, it's something we'd love to revisit," he said.

"Shooting Parliament House, shooting all around the city, it was all very possible and I think the end result on camera was kind of spectacular.

"[Canberra] is a new landscape for Australian television."

Those familiar with Canberra were quick to point out where the makers of the series had stretched the bounds of possibility, such as the location of the kebab van nestled under Kings Avenue bridge in episode one or the likelihood of the main character being able to park his aging Peugeot outside Parliament House without a batted eyelid from security.

But Taylor said the series' quirks were deliberate.

"It was part of the story and part of the decision making process was always to find some iconic and spectacular locations within Canberra to set the scenes that were written," he said.

"We just made some choices that would jump off the screen and we don't regret doing that.

"I think it turned out really well."

Taylor said the series' producers were happy with the response from all viewers since the series had wrapped in Australia and the UK and been made available for download in the US ahead of its release to the rest of the world.

"We've had comment from all quarters and it's all been extremely positive," he said.

"It's been a real journey and we're very proud of it."

Mr Taylor said the social media buzz around the series and its final episode on Sunday had been "more than welcomed".

"We've had a huge response both locally and internationally which has been exciting for all of us," he said.

But he hosed down suggestions from fans that the final scene had been deliberately left open ended.

"I don't think it was about setting up for a second series it was more just to keep people thinking of the story that unfolded and all the possible ramifications of what happened over those six hours," he said.
