ARTICLES

Understanding Ballistic & Forced Entry Protection

Terms like “bullet-proof” or “burglar-proof” are often used loosely. But in reality, there is no such thing as completely impervious protection—only tested, certified levels of resistance matched to realistic threats. This article provides a breakdown of what these resistance ratings mean, how they’re tested, and how to match them to real-life threat scenarios.

Selecting the Right CBRN Air Filtration System

A reliable CBRN air filtration system is the cornerstone of an all-hazard shelter, delivering clean, breathable air in the presence of toxic atmospheres due to nuclear fallout, chemical releases, smoke, or biohazards. This article provides a comprehensive guide to selecting the right CBRN filtration system, emphasizing key considerations for airflow volume, performance, reliability, and long-term readiness.

The Ultimate Guide to Surviving Nuclear Radiation

This article the different types of radiation released from a nuclear detonation, the radiation risks as a function of time and distance from the explosion the immediate and long-term health impacts of radiation exposure, protective measures, and guidelines for when it is safe to emerge from a fallout shelter.

Coronal Mass Ejections: Understanding the Threat and Preparing for the Impact of a Carrington-Scale Event

This article explores the nature of CMEs, the likelihood of a Carrington-scale event, the historical impacts of the 1859 storm, the potential modern-day, and how we can recognize and prepare for such an event.

High-Altitude Electromagnetic Pulse (HEMP) Threats to Australia: Mechanisms, Impacts, and Preparedness

This article examines how a nuclear device could maximize EMP damage, deployment strategies against Australia, the scope of impact, and likely adversaries, emphasizing their strategic motivations in broader conflicts. It details EMP’s effects on electronics, identifies vulnerable systems, how to recognise a HEMP event, and explores immediate and medium-term societal consequences. Preparation strategies and practical steps for governments and individuals are outlined.

Nuclear Threats to Australia: Risks, Impacts, and Preparedness

Australia’s strategic position and alliances, notably the AUKUS pact, elevate its exposure to nuclear risks in an increasingly volatile Indo-Pacific region. This article analyses likely targets, warhead characteristics, immediate and medium-term impacts and civilian preparedness measures. As far as possible, this article draws on authoritative sources such as Australian defence white papers, U.S. military reports, and declassified Cold War documents.
