Thanks for contribution.
These are listed as 'Jane Halifax f.p' (without IMDb link)
http://www.imcdb.org/movie_1004509018-Halifax-fp.html

'Jane Halifax f.p.' was played by Rebecca Gibney in all episodes of this TV series, but each episode was very long, 2 hours, maybe that's why they are listed as films.

Could be, like what we did for Columbo's 403 before that some of "his" movies were added.

All Columbo on IMCDb are listed as separate with sub-title.
How do we list this?
One idea is temporary list it as 'Halifax f.p:'...

It seems that like for Columbo and few others, IMDB listed that "series" as separate TV movies.

Many 'Halifax f.p:',Rebecca Gibney as Jane Halifax was found, which one?

I'd say 9-3

In the Australian TV series 'Halifax', the main character ms Jane Halifax (Rebecca Gibney) drives a Saab 900 or 9-3 convertible. First black, then silver and later a blue one. The blue one had licence plate "OZZ-030"
Vehicle role; *****
