About Mobilarm Ltd:

Headquartered in Perth, Western Australia, Mobilarm (ASX: MBO) is one of the world’s leading brands in the rapidly growing man overboard product category. The Company’s marine safety equipment solutions remove risk from the workplace in the offshore oil and gas, defence and commercial marine industries, where regulatory compliance, Occupational Health & Safety and Director’s Liability are the major drivers for improved employee safety and Duty of Care.
