After General Motors Co. (GM) plummetted to bankruptcy amid the 2009 financial crisis, its hope to launch the world-famous Cadillac in Australia were swept away with it.

But after CarsGuide posted photos of Cadillac CT6 sedans at Tullamarine Airport in Melbourne on Wednesday, Aussie consumers have reason to believe a surprise launch may be brewing. 

It was eager passersby who took the photos of the Cadillacs being brought into trucks. But Holden, GM's Australia-based subsidiary, said the CT6 sedans were in the country for a worldwide work share program that enlisted the help of engineers in the country to test GM vehicles, even those from outside markets.

But an opening for the Cadillac may occur soon after Holden halts production of its own luxury cars, the upscale Commodore model and long-wheelbase Caprice when 2017 comes to a close. The CT6 sedan, being an upmarket offering of about the same size as Holden's Caprice, could certainly fill its shoes. 

Top-level officials from the global company have not held back in proclaiming their strong desire to bring GM's cars to Australia by 2020. In both 2014 and 2015, global marketing officials of the iconic brand reiterated a plan to produce right-hand-drive cars.

Cadillac Chief Marketing Officer Uwe Ellinghaus, during the 2014 Detroit Motor Show, proclaimed that they wanted the vehicle to be globally competitive. This included Australia, wrote Motor Authority.

The brand, in its hopes to be the top choice for luxury sedans the world over, has already set up shop in China, the Middle East and Europe. 

Earlier in 2016, other Cadillac sightings had been reported in Melbourne like the CTS-V.  The latest Cadillac CT6 appearance seemed to feature base-models built with a 2.0-liter turbo engine that propels power to the sedan's rear wheels, as well as an all-wheel-drive, top-of-the-line Platinum CT6.
