Citadel Secure is your full-service partner in the Defence and Government sectors. With over 50 years of direct support to the Australian Defence Forces, we bring a unique perspective to domestic and international Defence industry engagement.

Founded in 2019 as a veteran-owned Adelaide-based company, our primary focus was on supporting Defence industry security. Over time, we’ve evolved into a fully integrated advisory firm, helping our partners build businesses that resonate with key stakeholders, foster partnerships and secure commercial opportunities for both domestic and international growth.

What sets Citadel Secure apart in the Defence industry is our extensive experience of working with both Australian and industry SMEs, as well as directly with Defence Primes and Sub-Primes, fostering partnerships and delivering success.

Uniquely, we have a proven track record of winning and delivering projects to Australian and New Zealand Government Defence organisations. Our multifaceted approach, spanning various sectors and geographies, positions us as a true industry leader in creating opportunities and building meaningful collaborations.

We are committed to delivering high-value projects and partnerships to ensure the success of our serving men and women. Our success is built on an unwavering commitment to delivering value through the smartest people, integrated technology solutions and world-class thinking. We prioritise our partner’s needs, providing cost-effective solutions and earning trust by taking problems away to maximise our partner’s productivity.

We cherish the lasting partnerships we’ve built with our clients. These relationships, founded on trust, assure our sustainability and contribute to your success.

We understand that trust is earned, and we never take it for granted.
