Night drone operations are expanding across Australia, enabling emergency response, infrastructure inspection, and specialized commercial work. However, CASA has strict rules governing when, where, and how drones can fly after sunset. This comprehensive guide covers the 2026 regulatory landscape, lighting requirements, exemptions, and best practices for compliant night operations.

The Fundamental Rule: Daylight Operations Default

Under CASR Part 101 and Part 102, all drones must operate during daylight hours unless explicitly authorized by CASA. The default rule is unambiguous:

Daylight hours = 30 minutes before sunrise to 30 minutes after sunset (civil twilight window)

Flying outside these times without written CASA approval is an automatic breach of Part 101/102 and can result in:

  • A$2,000–A$10,000 fine for first offense
  • License suspension for repeat violations
  • Aircraft confiscation in serious cases

What Counts as "Daylight"?

CASA defines daylight precisely:

  • Start: 30 minutes before official sunrise (Bureau of Meteorology data)
  • End: 30 minutes after official sunset (same source)

This twilight window exists because aircraft lighting becomes visible and useful at these times, though visual conditions are diminishing. CASA requires operators to use actual Bureau of Meteorology times for their location, not estimates.

Example: If sunset in Sydney is 17:45 on April 15, night flying cannot legally commence until 18:15. Operating at 18:10 is a breach.

Exemptions and Night Flying Approvals (2026)

CASA grants night flying authorization in three categories:

Category 1: Standard Night Flying Approval (Trial Operations)

Eligibility: Commercial operators with:
  • Valid CASR Part 102 RPAO certificate
  • Minimum 200 hours documented flight time
  • Specific night operations training certificate
  • At least one manned aircraft pilot on standby (in same location)

Authorization scope:
  • Limited geographic area (typically 5–10 km radius)
  • Restricted altitude: 60 meters AGL maximum
  • Time window: 1 hour after sunset to 1 hour before sunrise
  • Weather: Clear conditions only (visibility minimum 2 km)
  • Aircraft: Must carry functioning navigation lights

Application timeline: 6–8 weeks Approval period: 12 months (renewable annually)

Category 2: Extended Night Flying (Full Part 102 Approval)

Eligibility: Established commercial operators with:
  • 2+ years Part 102 operational history
  • Zero safety incidents or regulatory violations
  • Comprehensive Risk Assessment for night operations
  • Advanced Detection & Avoidance system (see below)

Authorization scope:
  • Unlimited geographic area
  • Altitude: Up to 120 meters AGL
  • Time window: 30 minutes after sunset to 30 minutes before sunrise
  • Weather: Can operate in marginal visibility with DAA confirmation
  • Aircraft: Dual navigation lights + anti-collision strobes

Application timeline: 8–12 weeks Approval period: 24 months (biennially renewable)

Category 3: Essential Services Exemption

Emergency responders (fire, police, search & rescue) may apply for:

  • 24-hour operational authorization
  • Unlimited flight altitude
  • Any weather conditions
  • Simplified approval process (2–4 weeks)

Requirement: Valid government authorization letter from relevant agency (Fire & Rescue NSW, Victoria Police, etc.)

Mandatory Lighting and Detection Equipment

Navigation Lights (Anti-Collision Lights)

CASA mandates:

  • Red light (left wing tip, or port-side fuselage)
  • Green light (right wing tip, or starboard-side fuselage)
  • White light (tail, or rear fuselage)

Each light must:

  • Have minimum intensity: 400 candlepower
  • Blink at 60–90 flashes per minute
  • Remain powered throughout flight
  • Survive night flight duration (backup battery required if flight exceeds 1 hour)

Anti-Collision Strobes

For extended night operations (Category 2), strobes are required:

  • White strobing light on fuselage (additional to nav lights)
  • Minimum 2 Hz flash rate, visible from 1,000 feet away

Detection & Avoidance (DAA) Systems

For night flying beyond 60 meters AGL, CASA requires:

  • ADS-B receiver — Detects other aircraft transponders
  • Radar altimeter — Confirms altitude to ±10 feet
  • Real-time telemetry link — Ground station monitors aircraft position and status
  • Obstacle detection sensor — Optical or thermal (forward-looking)

Total cost for approved DAA package: costs vary significantly depending on the drone and accessories chosen.

Night Lighting Installation Checklist

Pre-Flight (Night Operation Specific)

  • Verify all three navigation lights function and battery level >90%
  • Check strobe intensity and flash rate (if required)
  • Test telemetry link range (minimum 3 km coverage)
  • Confirm DAA radar/ADS-B activation and signal strength
  • Review weather conditions and visibility forecast
  • Verify ground crew briefing on emergency procedures

Flight Management

  • Maintain altitude within approved limit (60m or 120m per authorization)
  • Monitor telemetry display continuously (do not fly autonomously)
  • Reduce speed to 20 kph or less to maintain visual control
  • Maintain communication with ground safety observer on dedicated radio frequency
  • Turn on all lights 10 minutes before departure and keep on until full landing

Post-Flight

  • Document flight duration, lighting status, and any anomalies
  • Record all telemetry logs (CASA requires 2-year retention)
  • Check light fixtures for damage or corrosion
  • Verify battery charge and schedule maintenance if below 95% capacity

Environmental and Safety Considerations

Noise Restrictions

Night flying is subject to noise limits even with approval:

  • Maximum sound level: 70 dB at ground level, 100 meters from flight path
  • Most consumer drones exceed this; professional models (DJI M300, Freefly) fall under limit
  • Operations near residences limited to 2 hours per night (consecutive or split)

Light Pollution and Wildlife

  • Avoid flights over wildlife habitats, particularly migratory bird corridors
  • Do not operate near airport beacon or navigation lights
  • Minimize strobe flashing duration when transiting near residential areas
  • Environmental assessment may be required if operating near protected areas

Observer Requirements

CASA mandates a Visual Observer (VO) for all night operations:

  • VO must have unobstructed view of the aircraft
  • VO uses night-vision goggles (recommended) or spotlight
  • VO maintains real-time radio communication with pilot
  • VO role may be remote (via video link) only with explicit CASA approval and under Category 2 authorization

Common Compliance Gaps in Night Operations

Gap 1: Operating without formal night approval

Flying after sunset with standard Part 102 authorization is a breach. Many operators assume Part 102 permits night flying—it does not. Night authorization must be explicitly mentioned in your approval certificate.

Gap 2: Inadequate lighting installation

Lights mounted on the fuselage pointing downward will not be visible to other aircraft. Lights must be laterally separated (wing tips) and aimed perpendicular to the fuselage. A single light is insufficient; all three (red, green, white) are required.

Gap 3: No Visual Observer

Flying autonomously or with video-link-only observation without CASA pre-approval is non-compliant. Even with DAA systems, CASA mandates a physical observer on-site during night operations.

Gap 4: Telemetry link failures

Night operations depend entirely on the telemetry link to the ground station. If signal drops, you must land immediately. Operating beyond 3 km telemetry range, or in areas with RF interference (near cellular towers, airports), is non-compliant.

Application Process for Night Flying Approval

FAQ: Night Flying Regulations

Piyo: "I have Part 102. Can I fly at dusk (7:45 PM) without special approval?"

No. Dusk is after the 30-minutes-after-sunset window. If sunset is 17:45, your legal window closes at 18:15. Flying at 18:45 requires formal night operations approval—unless you're within the twilight window, it's a breach.

Poppo: "What if my drone has only one light (white tail light)?"

Insufficient. CASA requires all three colors (red, green, white). A single white light can be confused with a star or distant aircraft. Install a proper lighting kit with laterally-separated red/green and aft white light.

Piyo: "Can a Visual Observer be off-site (watching via camera feed)?"

Only if explicitly authorized in your Category 2 approval. Standard night authorization requires the observer to be physically present and able to see the drone with naked eye or night-vision equipment. Camera feed is acceptable only as a supplementary tool.

Poppo: "If I'm operating under emergency services exemption, do I still need lights?"

Yes. Even emergency responders must follow lighting requirements. The exemption speeds up approval, but doesn't waive safety equipment mandates.

Piyo: "How do I renew my night flying approval?"
