The species is vulnerable to several anthropogenic hazards, one is barbed wire fencing that accounts for many deaths when they are snagged through the easily torn wing membrane while in flight. The damage caused by the barbed wire strands, often left littering their environment, is greatly increased as the individual become entangled as it attempts to dislodge itself. A study in the Pilbara region identified this as an especial concern, with indications that barbed wire was significantly impacting local populations when erected. The foraging height of "M. gigas" is around that of the dominant "Triodia" (spinifex) vegetation and the species is unable to visually detect the wire strand, and is not thought to use echolocation to forage in flight. The thorny and tangled introduced plant lantana also presents a similar hazard to bats. They are especially sensitive to disturbance in wintering roosts, and a single fleeting visit will see the site deserted for several weeks or altogether if human activity continues. Most bat species are vulnerable to human disturbance, but attempts to view "M. gigas" at their roosts are especially discouraged due to the rapid decline in range and population. New or reopened mining operations may have an impact on local colonies, although they may provide diurnal roosts when complete; they are vulnerable to dilapidation in former mines such as the collapse of ceilings.
