Hill (1998) included Macrozamia machinii with M. plurinervia, which occurs between Inverell and Tenterfield in northern New South Wales. The Queensland Herbarium does not accept this synonymy (Queensland Herbarium 2013) and, for the purpose of the Environment Protection and Biodiversity Conservation Act 1999, M. machinii is treated as endemic to Queensland. Sharma and colleagues (2004) showed that although species in the M. plurinervia group are closely related, morphological characters reinforce the separation of M. machinii.

The distribution of Macrozamia machinii and M. plurinervia do not overlap and they grow in different habitats, with M. plurinervia occurring in hilly country with large granite outcrops prominent and gravelly loam soil, whereas M. machinii grows in flat plains and breakaways on deep sandy soils (Jones & Forster 1994). Also, M. machinii has thicker leaflets that are dull green on both surfaces (grey-green to glaucous in M. plurinervia), smaller cones and smaller, oblong to ovoid seeds (broadly ovoid to oblong ellipsoid in M. plurinervia) (Jones & Forster 1994).

Macrozamia machinii occurs on the Darling Downs in Queensland between Texas and Wondul Range National Park (ALA 2013). When described, there were eight populations near Inglewood (Jones & Forster 1994). Three of the sites are in state forests, while the remaining sites are on leasehold land (Qld DNR 2000).

Most Macrozamia machinii populations occur in deep sandy soils in flat areas of open forest dominated by Angophora leiocarpa, Allocasuarina inophloa, White Cypress-pine (Callitris glaucophylla), Budgeroo (Lysicarpus angustifolius) and Crowded-leaf Wattle (Acacia conferta) (Jones & Forster 1994; Hill 1999a). However, one population occurs on a red lateritic ridge with Black Cypress-pine (Callitris endlicheri), Tumbledown Ironbark (Eucalyptus panda) and Western Yellow Stringybark (E. apothalassica). The species is found at 320-460 m above sea level (Jones & Forster 1994).

Macrozamia machinii cones mature in September to December and seeds ripen February to April (Jones & Forster 1994). Beetles are thought to effect cross-pollination between individuals (Qld DNR 2000). Populations show little obvious recruitment, perhaps because the putative pollinators are not present (Forster 2004b).

Fires in some populations between July and September have often been followed by massive cone and seed production two years later (Forster 2004b).

Possible threatening processes to Macrozamia machinii include (Qld DNR 2000):

  • inappropriate legal collection
  • illegal collection (seedlings and mature plants) for horticulture
  • disturbance of habitat (by timber harvesting)
  • destruction of habitat (by clearing)
  • inappropriate fire regimes
  • deliberate killing by poisoning (it's targeted because leaves and fruit are poisonous to domestic stock if ingested).

Macrozamia spp. in the Darling Downs is likely to contract and move upslope as a result of climate change (Laidlaw & Forster 2012). Habitat fragmentation and the species restriction to smaller refugia in this area limits the potential for natural migration in response to climate changes (Laidlaw & Forster 2012).

In 1999, 67 mature individuals (mostly female) were illegally removed from the type locality on crown land (Forster 2004b).

The following table lists known and perceived threats to this species. Threats are based on the International Union for Conservation of Nature and Natural Resources (IUCN) threat classification version 1.1.
