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
The Norinco 77B in an 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 movie 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). Although Police in several Australian states and territories have employed .357 revolvers until replacing them very recently with .40-caliber Glock or Smith & Wesson M&P series semi-automatic pistols, the Colt Combat Python has never been a regulation sidearm with the Australian Police.
Micro UZI
The Micro Uzi submachine gun, 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 forends. 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.
