What Great Southern Security does

Great Southern Security (legal entity: Great Southern Security Service) is a privately held, family-owned security services provider headquartered in Goolwa Beach, South Australia, founded in 2002 and acquired by Ian and Michelle Haylock in 2022. The company delivers integrated electronic security solutions across South Australia with concentration on the Fleurieu Peninsula, operating an in-house Grade A monitoring bureau for 24/7 back-to-base alarm monitoring, mobile patrol response, and a multi-vendor technology stack spanning CCTV (LTS, Hikvision, Hanwha, Axis), access control (Inner Range, Honeywell, Aiphone), intrusion detection (Hills, Paradox, Assa Abloy), and video management software (Milestone).

Its service portfolio includes security system installation, camera and CCTV, 24/7 alarm monitoring, mobile patrols, access and control systems, static guards and event security, cash transit services, test & tag compliance, and maintenance and repairs, plus specialty lines in building site security and boat/marina security. Revenue is generated through a mix of one-time installation fees, recurring subscription monitoring and patrol contracts, and professional services engagements (guards, cash transit, test & tag), with quote-based pricing and multi-year contracts. The go-to-market is direct sales via phone, website quote requests, and on-site consultations, supported by ASIAL membership and word-of-mouth referrals, serving both residential and commercial customers with named enterprise and government logos including SA Water, City of Victor Harbor, City of Alexandrina, Foodland, Worley, and Hotel Elliot.
