Weep holes and ground clearance in Austral NSW
Weep holes come up more often across the Austral jobs than almost anything else: missing entirely from a run of brickwork at lock-up, still missing at fixing stage, and at handover either required outright or present but with a clearance under the 150 millimetres the standard asks for. They matter twice over. They drain the cavity, so water that gets behind the brick can leave rather than sit against the frame. And the clear gap between the weep hole and the ground is the zone where termite activity would have to become visible.

A cavity wall takes water, and weep holes are how it gets back out.
The clearance above finished ground is generally 150 mm, or less over graded paved surfaces.
Ground built up over the weep holes removes the drainage and the inspection zone at once.
Missing weep holes were recorded at lock-up, fixing and handover on Austral jobs.
Both problems are cheap to correct while the builder is still on site.
