The Northern Hopping-mouse is assessed as Endangered because its extent of occurrence (EOO) is less than 5,000 km², all individuals occur in fewer than five locations, there is continuing decline in the extent and quality of its habitat, and decline in population size and area of occupancy (AOO). In contrast, Woinarski et al. (2014) considered it to be Vulnerable A2be+3be+4be. Assessment of this species is challenging given the very limited information available on distribution (and hence number of locations), population size, and extent of its decline. It is more likely than not that the species is no longer present on the Australian mainland, so an EOO of ca 2,300 km² (the area of Groote Eylandt) is plausible. It is more likely than not that the population size, habitat quality and AOO are all undergoing continuing decline on Groote Eylandt.

|Range Description:||This species is endemic to Australia where it is restricted to coastal areas in north-eastern Arnhem Land and Groote Eylandt in Northern Territory. The type specimen was reportedly collected on the Cape York Peninsula, Queensland some time prior to 1867, however, the species has not since been recorded here (Winter and Allison 1980, Lee 1995, Woinarski and Flannery 2008), and the provenance may be dubious. There have been no confirmed records on the Australian mainland for >20 years, with all recent records coming from Groote Eylandt (Woinarski et al. 2014).|
