Oversized and heavy-lift cargo presents unique challenges when transported by air, especially across Australia’s remote regions and island territories. From mining machinery to modular infrastructure, these shipments exceed standard dimensions and weights—and require aircraft with specialised capabilities. Freight charter is often the only viable way to deliver these loads where road or sea access is too slow, restricted, or simply unavailable.
This guide explores the best aircraft types, technical considerations, and pricing factors for oversized and out-of-gauge (OOG) air cargo charters in Australia.
Oversized or out-of-gauge (OOG) cargo includes any load that exceeds standard container or ULD (Unit Load Device) dimensions, or that weighs more than 10 tonnes per piece. Examples include:
Mining crushers and haul truck components
Wind turbine blades
Military vehicles and bridge spans
Satellite equipment and telecom towers
These items often require non-standard packaging, reinforced pallets, or crane-based loading.
Depending on the load’s weight, size, and route, operators typically use:
| Aircraft Type | Max Payload | Loading Type | Range |
|---|---|---|---|
| L-382 Hercules | 20,000 kg | Rear ramp | ~3,800 km |
| Antonov An-124 | 120,000 kg | Nose + ramp | ~4,500 km |
| Boeing 747-8F | 135,000 kg | Side cargo door | ~8,000 km |
| Ilyushin IL-76TD | 50,000 kg | Rear ramp | ~4,200 km |
Aircraft choice depends on cargo dimensions, route, and airport facilities (e.g., pavement strength).
Cargo that can’t fit through standard freight doors must use aircraft with wide openings or ramps. For example:
An-124: Nose opens upward; allows straight-on loading of vehicles or modular units.
Hercules: Rear ramp allows roll-on/roll-off operations, often used in mining logistics.
B747F: Side cargo door; max height ~3 m, suitable for palletised high-value cargo.
Shippers must provide CAD drawings or diagrams for pre-clearance.
Heavy-lift charters require:
Runways ≥ 2,500 m and rated for high MTOW (e.g., Perth, Darwin, Brisbane)
Apron space for cranes, flatbed trucks, or forklifts
Ground handling teams trained in OOG/oversized cargo
Remote strips may need temporary upgrades or alternative delivery (e.g., to nearby major hub + road leg).
Pricing is calculated per flight hour or tonne-kilometre (tkm), influenced by:
Aircraft type and fuel burn
Distance and repositioning
Airport fees and ground handling
Insurance and risk premiums
Example: Brisbane to Port Moresby (Antonov An-124): $320,000–$450,000 depending on load and handling.
Cargo: Excavator housing (6.2 m x 3.5 m x 3.4 m)
Route: Perth → Port Moresby
Aircraft: Ilyushin IL-76TD
Result: Delivered within 72 hours of breakdown, preventing $1.2M in operational downtime for mining client.
