Eremophila tietkensii is a rounded or flat-topped shrub which grows to a height of between 0.6 and 2.5 m (2 and 8 ft) with its branches and leaves covered with a layer of fine grey hairs pressed against the surface.
The leaves are arranged alternately, well spaced along the branches, grey-green and have a flattened stalk that is 6–12 mm (0.2–0.5 in) long.
The leaf blade is lance-shaped to egg-shaped, mostly 30–72 mm (1–3 in) long, 6–17 mm (0.2–0.7 in) wide and has a smooth surface.


The flowers are borne in groups of up to 4 in leaf axils on a hairy stalk which is usually 6.5–14 mm (0.3–0.6 in) long.
There are 5 overlapping, elliptic to lance-shaped, green or pinkish-purple sepals which are mostly 7.5–15 mm (0.3–0.6 in) long.
Both surfaces of the sepals are hairy, especially around the edges and are usually more hairy on the outer surface.
The petals are 22–28 mm (0.9–1 in) long and are joined at their lower end to form a tube.
The petal tube is pale lilac to pale mauve or pink on the outside and white with purple spots inside the tube.
The outer surface of the petal tube is slightly hairy but the inner surface of the lobes is glabrous while the inside of the tube is filled with long, woolly hairs.
The 4 stamens are fully enclosed in the petal tube.
Flowering occurs between April and October and the fruit which follow are dry, woody, oval to conical in shape with a distinct point and 6–7 mm (0.2–0.3 in) long.
