Production on the long-awaited spin-off series featuring K9 is due to start in Australia next month, according to the Pacific Film and Television Commission.
An article in its June newsletter says that Bob Baker is currently in Queensland, writing the 26-part show. He co-created the character of the robot dog with Dave Martin, who died in March 2007.
According to the PFTC, Baker is working on the spin-off - called simply K9 - with Queensland writers Shayne Krause and Shane Armstrong.
It is being produced by Simon Barnes, and Richard Stewart and Penny Wall from Brisbane company Stewart Wall Entertainment.
A PFTC spokesman told The Doctor Who News Page: "The series certainly is imminent! K9 is in pre-production at present in Queensland. However, exact dates for production have not yet been confirmed."
Outpost Gallifrey reported last July that an unspecified amount of funding had been approved by Australia's Film Finance Corporation.
TV distribution agent Park Entertainment has said the half-hour episodes, to be made by Jetix Europe, will be live action and CGI.
