Drone Airspace Classification Australia 2026

Australian airspace is divided into distinct classifications, each with specific rules governing drone operations. Understanding airspace classification is fundamental to legal drone operations and essential for CASA compliance. Airspace classification directly determines what you can and cannot do.

ICAO Airspace Classification System

Australia uses the International Civil Aviation Organization (ICAO) airspace classification system, which divides airspace into Classes A through G. Each class has specific operational rules.

ICAO Classes:

Class A - Controlled; IFR only (no drones)
Class B - Controlled; IFR and VFR (restricted)
Class C - Controlled; IFR and VFR (moderate restrictions)
Class D - Controlled; IFR and VFR (lower restrictions)
Class E - Controlled airspace (above typical drones)
Class F - Uncontrolled; unrestricted use
Class G - Uncontrolled; unrestricted use

Drones typically operate in Class D, E, F, or G airspace. Classes A, B, and C are restrictive due to commercial aviation activity.

Class B Airspace

Class B airspace includes major international airports and their immediate surroundings. This is the most restrictive airspace.

Class B Characteristics:

High-density commercial aviation activity
Controlled from major terminal radar approach control
Typically extends 50+ km from airport
Multiple levels of altitude control
Very restrictive for drone operations

Drone Operations in Class B:

Drones generally prohibited without explicit CASA approval
Approval is rare and requires exceptional justification
Extensive safety procedures required
Coordination with ATC mandatory
Only commercial operations with specific need granted approval

Most operators should avoid Class B airspace entirely.

Class C Airspace

Class C airspace surrounds major metropolitan areas and busy regional airports. This is heavily controlled airspace.

Class C Characteristics:

Commercial aviation but less busy than Class B
Controlled airspace with altitude restrictions
Typically extends 20+ km from airport
Multiple altitude layers
Complex airspace requiring careful attention

Drone Operations in Class C:

Operations possible with CASA approval
Approval requires detailed safety procedures
Lower altitudes typically required (120-300m)
May require ATC notification or coordination
Proximity to airport significantly restricts altitude

Operators in Class C areas must have explicit CASA approval.

Class D Airspace

Class D airspace surrounds smaller regional airports and some metropolitan areas. This is moderately restrictive.

Class D Characteristics:

Controlled airspace for airport access
Less congested than Class B/C
Typically extends 5-10 km from airport
Altitude controls typically lower than Class C
Generally more permissive than higher classes

Drone Operations in Class D:

Operations possible with CASA approval
Approval typically easier to obtain than Class C
Moderate altitude restrictions (typically 120-400m)
May require notification to ATC
Cloud clearance requirements still apply

Class D airspace is moderately accessible for commercial drone operations.

Class E Airspace

Class E airspace is controlled upper airspace used for commercial aviation transits. This airspace is high altitude.

Class E Characteristics:

Extends from specific altitude (typically 3,000-10,000 feet AGL) upward
Commercial aircraft commonly transit
Not relevant for most drone operations
Above normal drone operational altitude

Drone Operations in Class E:

Drones operate below Class E airspace
Generally not a constraint for typical operations
Operations above 500m may approach Class E boundaries
Cloud clearance requirements more significant at drone altitudes

Class F Airspace

Class F airspace is uncontrolled but restricted for specific purposes. These areas have temporary restrictions.

Class F Characteristics:

Uncontrolled airspace with restrictions
Often used for military operations or special activities
Restrictions published via NOTAMs
May be activated only during specific times

Drone Operations in Class F:

Generally accessible when not activated
Restrictions take effect during scheduled times
Operators must monitor NOTAMs for temporary restrictions
Check current restrictions before operations

Class G Airspace

Class G is uncontrolled airspace with minimal restrictions—the most common airspace for drone operations. This is where most operators work.

Class G Characteristics:

Uncontrolled airspace with no ATC
No ATC coordination required
Generally permissive for drone operations
Still subject to CASA Part 101/102 rules
Cloud clearance and altitude limits still apply

Drone Operations in Class G:

Operations permitted under Part 101 (recreational)
Operations permitted under Part 102 (commercial) with approval
No ATC coordination needed
Visual line-of-sight maintained
Altitude and cloud clearance rules still enforced

Most recreational and some commercial drone operations occur in Class G airspace.

NOTAMs and Temporary Airspace Restrictions

Airspace classifications may be temporarily changed or restricted via Notices to Airmen (NOTAMs). These are critical for compliance.

NOTAM Types Affecting Drones:

Airshows - Temporary Class F activation during event
Military Operations - Temporary airspace restrictions
Special Events - Temporary height restrictions during events
Hazards - Flying hazards like aerial work or helicopter operations
Infrastructure Work - Construction and tower work

NOTAM Monitoring:

Check NOTAMs before every operation
AirservicesAustralia publishes current NOTAMs
Planning software often integrates NOTAM data
Last-minute updates possible—check immediately before flight

Determining Airspace Classification

Finding out what airspace classification applies to your operational area requires research. Multiple resources available.

Searchable by location
Shows airspace class and altitudes
Updated regularly for changes

AirservicesAustralia Resources:

Airspace class information
Altitude restrictions by location
NOTAM current information
ATC frequency assignments

Third-Party Tools:

Airmap, DroneSense, and similar services
Integrate CASA data with real-time information
Often easier to use than raw data sources
May include additional useful information

Altitude Limits by Airspace Class

Altitude constraints vary significantly by airspace classification. Understanding these is essential.

Typical Altitude Limits: Class B:

Drones generally not permitted

Class C:

120-300 meters typical
Varies by proximity to airport

Class D:

120-400 meters typical
Depends on airport activity

Class E:

Not typically relevant (above normal drone operations)

Class F:

When not activated: uncontrolled airspace rules
When activated: specific restrictions apply

Class G:

Part 101: 120 meters maximum
Part 102: approved altitude (varies by approval)

Always verify specific altitude limits for your location.

Coordination and Notification Requirements

Some airspace classifications require ATC notification or coordination. Requirements vary by airspace.

Notification Requirements: Controlled Airspace (B, C, D, E):

Often require ATC notification
May require approval before operation
Coordination frequency may be specified
Follow-up checks may be required

Uncontrolled Airspace (F, G):

Generally no ATC notification required
However, check for special NOTAMs
Courtesy notification sometimes appreciated
Follow local conventions

Approval documentation specifies notification requirements.

CASA Approval and Airspace

Your Part 102 approval specifies airspace where you're authorized to operate. Operations outside approved airspace violate regulations.

Approval Typically Includes:

Specific geographic area or location
Airspace classes where operations permitted
Altitude limitations for each airspace
Notification or coordination procedures
Frequency assignments if applicable

Operators must operate only in airspace specified in approval.

Integration with Flight Planning

Airspace classification must be integrated into flight planning before operations.

Flight Planning Airspace Considerations:

Identify operational area airspace classification
Determine altitude limits for that airspace
Plan mission within altitude constraints
Identify NOTAMs affecting operational area
Plan ATC notification if required
Brief team on airspace-specific procedures

Modern flight planning software integrates airspace data.
