Termite management notices in Leppington NSW

Every new house with a termite management system is supposed to carry a durable notice recording what was installed and when, usually fixed inside the meter box. We recorded it not found at lock-up on one Leppington job and not installed at all at fixing stage on another. It sounds like paperwork and it is not. Without that notice, a pest inspection ten years from now cannot tell whether a system exists, what type it is, or whether its service life has run out, and neither can you when you come to sell.
