Hello,
I am trying to ascertain the title of a film which I have so far been unable to track down.

It is a dark-comedy, sci-fi, horror set in a rural outback town in Australia, although from memory, the language spoken in the film is French. Aliens or monsters shaped like floating balls with draping tentacles slowly (unbeknown to the ever dwindling townsfolk) wipe out the population of the town, until they arrive at the local pub/hotel. There is a swamp/lake featured in the film also. SBS in Australia has screened this film on numerous occasions, though for the life of me I cannot remember any more than these vague details.

Any help would be greatly appreciated.
