AUKUS Supplier Directory is an online business directory connecting users with defence industry suppliers and vendors across Australia, the United Kingdom and the United States. It is designed to help organisations and buyers identify manufacturers, exporters and service providers relevant to defence and military supply needs. Visitors can search by category, business name, keyword or location, with advanced search options to refine results.

The directory spans a broad range of capabilities, including aerospace and aviation, ships and maritime equipment, vehicles, communications, electronics, protective equipment, engineering, manufacturing, software, logistics, training and consultancy. Its listings also cover specialist products and services such as aircraft components, armoured vehicles, batteries, sensors, cybersecurity-related systems, maintenance, testing and certification. Businesses can create a sponsor profile, while users can sign in to access the directory.

By organising suppliers across extensive product and service categories, AUKUS Supplier Directory provides a searchable resource for discovering companies that support defence and related industries in the three AUKUS partner countries
