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.
