“We’re not filming at the moment but the official line is a decision has not yet been made,” Erik Thomson told TV Tonight.
“That’s the official line, so read between it if you will.”
He said the production has “an ending of sorts” that could effectively be the finale if the network decides not to produce a seventh season.
“We’ve reached a conclusion that could be the end. There are talks that it might continue in a different format, telemovies or miniseries or whatever,” he said.
“I don’t think the franchise is necessarily dead but the series, as it stands, looks like it might have resolved.
“It’s sort of in the hands of the network at this stage.”
Next week Seven airs Episode 22 of Season 5 but rolls straight into Season 6 a week later.
“We’ve done 122 episodes, we’ve had 6 series with 5×22 and 1×12 episode series. It’s been really successful and you want to carry on knowing you can maintain that success. That’s a lot of hours of television for what is quite a high quality drama.
“A lot of stories have been told, a lot of people have come and gone. Whether we can continue to do that and still hold our heads up high, I’m not sure.
“But that’s in someone else’s hands.”
Seven’s drama slate is hardly lean with Home & Away, Winners & Losers, A Place to Call Home and Never Tear Us Apart: The Untold Story of INXS.
Meanwhile Thomson is filming The Broken Shore for ABC1, playing Inspector Villani of Irish-Italian descent.
“The Broken Shore is a telemovie with the ABC and it’s very exciting. I’ve only had one day’s work on it but I have a few more coming up at the end of the month.
“It’s a great cast in a dark, Aussie thriller based on a Peter Temple book of the same name, shooting in Melbourne and Port Fairy.’
“I’m an actor in Australia so I’m able to do anything really,” he said.
Packed to the Rafters airs 8:30pm Tuesdays on Seven.
