Austromyrtus dulcis is a small spreading shrub; 1 to 2 m (3 ft 3 in to 6 ft 7 in) in height. The leaves are 1–3 cm long and 0.5 cm wide, opposite, lanceolate to elliptical, glossy above with silky hairs beneath. The small white flowers are 7-10 mm in length, they have five petals and a large number of sepals, they are then followed by dotted mauve sweet edible berries which ripen in summer and autumn and contain three to nine pale brown seeds.^[3][4]

The species occurs in New South Wales and Queensland,^[5] from Grafton to Fraser Island. It occurs as a common understorey plant of heathland and woodlands and also growing on sandy soils and occasionally on the margins of rainforests.^[2][4]

The berries are a popular traditional bushfood, eaten by indigenous Australians and non-indigenous people. The melt-in-the-mouth berries are sweet and aromatic, with a pleasant peppery/gingery flavour. While recognized as having good flavour qualities, the berries have not been commercialized due to harvesting and handling issues.

Midgim is also popular in amenity horticulture as an adaptable shrub for a variety of situations, handling a range of soils and climatic conditions.

It springs up and grows like a wheat field .... one can go through acres of the scrub with its white, sweet-tasting berry until stopped by lagoon or salt water. It is the most sought-for berry or fruit on the island. Children will collect it by the tin-full, and even the elders will join with gusto in its eating.
