Brid, EGL, EGU, GipP, Glep, VVP. Also Tas. Scattered through near-coastal heaths in sandy loam or peaty soils east from French Island and apparently rare.

More westerly collections from grasslands in the Portland to Hamilton region, reputed to be of P. parviflorum, are possibly referrable to P. suaveolens, but are in need of study. Diminutive plants from the lower Glenelg River, Mt Richmond N.P. and Bats Ridges are also in need of study (see Prasophyllum aff. parviflorum).
