I suspected this would happen soon. Apparently Franchise Entertainment Group - the business that oversaw Blockbuster, Video Ezy and EzyDVD - ended their agreement with the US trademark holder. All Blockbuster stores in Australia were then required to rebrand within a certain time frame.
That eliminated a lot of Blockbuster stores in Australia all at once around January last year, including some stores that are still trading now, albeit under different names. In South Australia, Our Video Store (Blockbuster Morphett Vale) and Movieland Firle (Blockbuster Firle) continued trading until January 31st and February 28th respectively. Fairview Video (Blockbuster Fairview Park) is still trading.
Blockbuster Morley was the last remaining Blockbuster in Australia because they continued using the Blockbuster branding as long as possible. According to Ten News, it sounds like the trademark holder called time on that, and sealed their closure in the process.
Also, some of the last pieces. Some membership cards and keychain tags, the genre signs and some pricing cards, among other things.
Also another 100 or so DVDs that I haven’t had a chance to catalogue and shelve yet.
I also managed to track down and backup the MS-DOS based computer cataloguing and rental tracking system used by Blockbuster Australia, VideoMinder, from another long-defunct store (that shall remain nameless).
