Air Cargo Regulations in Australia: What Every Shipper Needs to Know

Regulations are the part of air freight that most shippers would rather ignore — right up until they get caught out by them. A shipment held at acceptance, a parcel rejected for an undeclared lithium battery, a fine for incorrect dangerous goods paperwork. I’ve seen all of these, and the common thread is always the same: the shipper didn’t know the rules applied to them.

Here’s the reality I’ve learned over two decades: air cargo regulation in Australia isn’t designed to make your life difficult. It exists for two serious reasons — safety (keeping hazardous goods from endangering an aircraft) and security (keeping the air cargo supply chain free of threats). When you understand the framework, compliance stops being a mystery and becomes just another part of shipping smart.

This guide breaks down the two big regulatory pillars every Australian shipper needs to understand: air cargo security and dangerous goods. Let’s demystify both.

Important: This article is general guidance only, not legal or compliance advice. Regulations change and your specific obligations depend on what and where you’re shipping. Always confirm current requirements with the relevant authority or a qualified expert before you ship.

Who Regulates Air Cargo in Australia?

The first thing to understand is that air cargo isn’t governed by a single body. Different authorities handle different aspects:

• Civil Aviation Safety Authority (CASA) — regulates aviation safety, including the consignment and carriage of dangerous goods by air.
• Department of Home Affairs — oversees aviation security, including air cargo screening and the schemes that keep the supply chain secure.
• Department of Infrastructure, Transport, Regional Development, Communications and the Arts — handles broader transport-of-dangerous-goods policy and international harmonisation.

In fact, the split is quite specific. In Australia, the Commonwealth is responsible for regulating the transport of dangerous goods by air through the Civil Aviation Safety Authority (CASA) and by sea through the Australian Maritime Safety Authority (AMSA), while the Australian states and territories have responsibility for road and rail transport of dangerous goods.

Knowing which body governs which issue helps you find the right answers — and the right help — when you need them.

Pillar 1: Air Cargo Security

The Legal Framework

Air cargo security in Australia rests on a clear legal foundation. Under the Aviation Transport Security Act 2004 and Aviation Transport Security Regulations 2005, all export and specified domestic air cargo must be cleared of unauthorised explosives prior to uplift onto aircraft.

In plain terms: before your freight goes on a plane, it must be confirmed free of security threats. There are two main ways this happens.

The Two Paths to “Cleared” Cargo

The Department of Home Affairs approves two routes for clearing air cargo. The Department of Home Affairs approves two options for air cargo to be cleared for transport by aircraft. Air cargo can either originate from a Known Consignor or be examined by a RACA.

Option 1 — Examination by a RACA. A Regulated Air Cargo Agent (RACA) examines your cargo at piece-level (carton by carton) using approved screening technology or physical inspection before it’s uplifted. For most occasional shippers, this is the default path — your freight forwarder or carrier handles the screening, often for a fee.

Option 2 — Originate from a Known Consignor. If your business is approved as a Known Consignor, your cargo is treated as already cleared. Cargo originating from a Known Consignor is considered cleared and does not need a piece-level examination by a RACA prior to uplift.

Should You Become a Known Consignor?

For regular, high-volume shippers, the Known Consignor scheme can be a genuine advantage — you avoid repeated screening fees and delays. But it comes with real responsibility. A Known Consignor is responsible for securing air cargo that originates from their business until it moves to another regulated business.

To qualify, known consignors must demonstrate that they have security measures and procedures in place and can secure their export air cargo from where it originates, until it is handed to another regulated business.

The scheme itself is free to join, but meeting the standard isn’t free. There are no fees to become a Known Consignor, and if you export regularly, applying to become a Known Consignor could be of substantial benefit. However, you’ll need to invest in things like secure packing and storage, security-related equipment, staff security awareness training, and employee vetting. The trade-off is that approved Known Consignors can issue their own security declarations and skip per-shipment screening.

My advice: if you ship air freight occasionally, let a RACA handle screening. If air freight is a core, high-volume part of your business, investigate Known Consignor status — but go in with eyes open about the security obligations.

Pillar 2: Dangerous Goods (DG)

What Are Dangerous Goods?

Dangerous goods are items that pose a risk to health, safety, property, or the aircraft. The list is broader than most people realise — common culprits include lithium batteries, aerosols, flammable liquids, certain chemicals, magnetic materials, and compressed gases. Many everyday products you’d never suspect are technically regulated for air transport.

The Rules That Apply

Australia’s dangerous goods rules for air are built on international standards. Part 92 of the Civil Aviation Safety Regulations (CASR) sets out the minimum safety requirements for the consignment and carriage of dangerous goods by air.

These domestic rules align with global frameworks. CASA follows the Technical Instructions for the Safe Transport of Dangerous Goods (Doc 9284) – international rules for carrying goods by air. Many airline operators also use the International Air Transport Association’s Dangerous Goods Regulations. This is why you’ll often hear the IATA Dangerous Goods Regulations (DGR) referenced — most airlines use them as their working rulebook.

The Shipper’s Responsibility

This is the part every shipper must internalise: the legal responsibility for dangerous goods starts with you. The shipper is ultimately responsible for ensuring the proper handling of dangerous goods.

That responsibility is detailed and non-negotiable. The shipper must classify, package, label, and document the goods accurately, ensuring they meet Australia’s national regulations as well as international standards. They are also responsible for completing a Dangerous Goods Declaration, detailing the nature of the materials and how they should be handled.

And declaration is mandatory — there’s no informal way around it. Shippers must declare all dangerous goods. Most operators will need a Shipper’s Declaration and an acceptance checklist completed by the receiving operator.

The consequences of not declaring are severe. Aircraft operators must refuse to load general cargo if a dangerous goods statement is not made. Beyond refusal, undeclared or mis-declared dangerous goods can result in serious penalties — and, far worse, they can endanger an aircraft and everyone on it.

Training Is Often a Legal Requirement

If dangerous goods are part of your business, the people involved likely need formal training. If your work involves the handling or transport of dangerous goods by air, or supervise staff whose work does, you must complete appropriate DG training to understand the associated risks and regulatory requirements.

CASA maintains advisory material specifically on this. Advisory Circular AC 92-01 provides information and advice on the regulatory requirements for dangerous goods training for employees of operators, cargo handling agents, freight forwarders, shippers of dangerous goods and screening authorities.

What Happens Behind the Scenes

Once you’ve correctly declared dangerous goods, the safety chain continues. Airlines must also complete a Notification to Captain (NOTOC), which ensures the pilot is aware of the nature and location of the dangerous goods on board. Operators are also required to use approved packaging and documentation, and some items are prohibited outright or permitted only under special approval.

One piece of practical wisdom from CASA worth heeding: where feasible, shippers should consider alternative modes of transport such as road, rail, or sea for high-risk dangerous goods. Sometimes the smartest compliance decision is simply not shipping a high-risk item by air at all.

A Practical Compliance Checklist

Before you ship, run through these questions:

• ☐ Does my freight contain anything that could be a dangerous good? (Batteries, aerosols, liquids, chemicals, gases.) If unsure, check — don’t assume.
• ☐ If yes, is it correctly classified, packed, labelled, and documented per CASR Part 92 / IATA DGR?
• ☐ Have I completed a Dangerous Goods Declaration where required?
• ☐ Do my staff have current DG training if they handle these goods?
• ☐ How will my cargo be security-cleared — via a RACA, or am I a Known Consignor?
• ☐ Is my paperwork accurate and complete (air waybill, descriptions, weights)?
• ☐ Have I disclosed everything honestly to my carrier or forwarder?

Tick these, and you’ve eliminated the vast majority of compliance problems before they start.

How This Connects to the Rest of Your Shipping

Regulations don’t sit in isolation — they touch everything:

• Packing must meet DG and security standards (see How to Pack and Prepare Your Freight for Domestic Air Cargo Shipping).
• Transit times are affected by screening — pre-cleared freight moves faster (see Domestic Air Cargo Transit Times).
• Carrier choice matters, as some carriers offer specialist DG handling (see our carrier comparison).

Compliance built into your process from the start saves you delays, fees, and headaches down the line.

When in Doubt, Get Expert Help

I’ll be blunt: if you’re shipping anything that might be a dangerous good and you’re not certain of the rules, don’t guess. The stakes — legal, financial, and safety — are too high. Talk to your freight forwarder, your carrier’s DG specialists, or a qualified dangerous goods consultant. The cost of expert advice is trivial compared to the cost of getting it wrong.

The same goes for security: a good RACA or freight forwarder will guide you through screening, and the Department of Home Affairs can advise on the Known Consignor scheme directly.

Frequently Asked Questions

Who regulates air cargo in Australia?
Aviation safety and dangerous goods are regulated by CASA under Part 92 of CASR. Air cargo security (screening, Known Consignor scheme) is overseen by the Department of Home Affairs.

Does all air cargo have to be screened?
Under the Aviation Transport Security Act and Regulations, all export and specified domestic air cargo must be cleared before uplift — either examined by a RACA or originating from a Known Consignor.

What is a Known Consignor?
An approved business that has demonstrated it can secure its air cargo from origin until it’s handed to another regulated business, allowing its cargo to be treated as cleared without further piece-level screening.

Who is responsible for dangerous goods compliance?
The shipper is ultimately responsible for correctly classifying, packing, labelling, documenting, and declaring dangerous goods.

What happens if I don’t declare dangerous goods?
Operators must refuse to load cargo without a proper dangerous goods statement, and undeclared DG can lead to serious penalties and genuine safety risks.

Do I need dangerous goods training?
If you or your staff handle or transport dangerous goods by air, appropriate DG training is generally required under the regulations.

Final Thoughts

Air cargo regulation in Australia comes down to two simple ideas: keep the aircraft safe (dangerous goods) and keep the supply chain secure (screening). Once you see it that way, the rules stop feeling like red tape and start making sense.

The shippers who never get caught out aren’t compliance experts — they’re just disciplined. They check whether their goods are regulated, they declare honestly, they get their paperwork right, and they ask for help when they’re unsure. Build those habits, and you’ll move your freight legally, safely, and without the nasty surprises that catch out everyone else.
