I saw this movie on TV a few years ago.
It seemed like it was from the 90’s or perhaps newer but the film quality wasn’t a big picture company.
It had accents that i’m assuming were Australian as it is set in the desert for a lot of it.
The ending was a guy and a girl in a jeep being chased by a spirit like giant kangaroo at night that was trying to kill them. They were trying to out run it it seemed to finnally shoot off into the night sky. and i can’t remember anything else. It was kind of a horror-esque movie. Kind of like Jacob’s Latter odd.
