The insufferably whiny Australian police constable Harrison (Dirk Hunter) uses a Remington 870 Slug gun, which he uses to blast a perfect hole through the lock on a heavy door, and later uses it to fight the zombies.
Marion (Mungo McKay) carries a Beretta 92FS amongst his other firearms during the zombie assault.
Satin Nickel M1911A1
Marion (Mungo McKay) uses a pair of matching Satin Nickel M1911A1 pistols to fight off the zombies.
Norinco 77B
This 9x19mm caliber pistol of Chinese manufacture, produced for export and commercial sales and featuring a peculiar single-handed-cocking device, appears several times during the movies in the hands of Wayne (Rob Jenkins).
Colt Combat Python
The 3-inch-barrel Colt Combat Python revolver (.357-Magnum) is used by the overly-nervous policewoman Molly (Emma Randall).
Micro UZI
The Micro-UZI sub-machinegun, or possibly an UZI-Pistol, briefly appears in the final sequences of the movie in the hands of an Australian soldier at the hospital.
Smith & Wesson 916A Shotgun
Marion (Mungo McKay) creates a bizarre contraption of three shotguns mounted together. Due to the barrels and the end of the magazine tube, the shotguns are possibly Smith & Wesson Model 916A riot shotguns. Though early in the film the shotguns have custom foregrips, later they are the standard S&W 916 style foreends. At the end of the film Rene, (Felicity Mason) is seen with the same three gun contraption, except with a Remington 870 added to the end, making it a cluster of four shotguns.
