Think registering your drone is optional? Think again. CASA requires registration for nearly all commercial RPA operations. This guide walks you through the process, costs, timelines, and what happens if you skip it.
Piyo: "I bought a DJI Matrice 300. Do I need to register it with CASA before I can fly?"
Moo: "If you're flying commercially (hold a ReOC), yes. CASA maintains a national RPA registry. Your aircraft must be registered, marked with your identifier, and you must carry proof during operations."
Who Must Register? The Quick Answer
| Operator Type | Commercial? | Must Register? |
|---|---|---|
| Hobby flyer | No | No |
| Micro RPA (<100g) | Any | No (under 100g exempt) |
| Commercial, ReOC holder | Yes | Yes, mandatory |
| Commercial, no ReOC | Yes | N/A (illegal anyway) |
Why CASA Requires Registration
- Accountability โ Link aircraft to operator; enables incident tracing
- Safety tracking โ CASA monitors aircraft age, accident history
- Airspace data โ Helps CASA understand where commercial ops occur
- Regulation compliance โ Proves operator meets CASR Part 101 requirements
CASA RPA Register: System Overview
Website: casa.gov.au/rpa-register Managed by: Civil Aviation Safety Authority (CASA) Data stored:- Aircraft type & model
- Maximum Takeoff Mass (MTOM)
- Registration owner (ReOC holder or organization)
- Current location
- Incident history (if any)
Poppo: "Think of CASA RPA Register like vehicle registration. Your rego number identifies your vehicle to police. Your RPA identifier tells CASA who operated that aircraft."
Step-by-Step Registration Process
Step 1: Prepare Documentation
Before logging into CASA's system, gather:
| Document | Details |
|---|---|
| ReOC Certificate | Certificate number, expiry date |
| Aircraft Details | Model, serial number, MTOM |
| Proof of Ownership | Receipt or invoice |
| Identification | Photo ID (to match ReOC holder) |
Step 2: Access CASA's RPA Register Portal
- Go to casa.gov.au/rpa-register
- Click "Register New RPA" (or "Log In" if existing account)
- Enter ReOC credentials (ReOC number + password)
- Authenticate via 2-factor authentication (SMS code)
Step 3: Input Aircraft Information
Required fields:- RPA Model: DJI Matrice 300 RTK, Freefly Alta X, etc.
- Serial Number: Found on battery, motor, or fuselage (alphanumeric code)
- Maximum Takeoff Mass (MTOM): In kilograms (45 kg for Matrice 300 without payload)
- Primary Use: e.g., "Aerial survey," "Infrastructure inspection," "Agricultural monitoring"
- Home Base: Where you operate from (address)
- Deployment Location: Where first mission will occur (optional, can change)
Moo: "If your Matrice 300 + batteries + payload = 52 kg, you must register 52 kg. Claiming 45 kg to skip insurance requirements is fraud and grounds for criminal prosecution."
Step 4: Review & Submit
CASA's system auto-validates:
- โ Serial number matches manufacturer database (if available)
- โ MTOM matches aircraft specs (alerts if anomaly)
- โ ReOC holder details are current
Step 5: Receive Registration Number & Certificate
CASA issues:- RPA Registration Number: Format like "VH-ABC123" (Airworthiness certification format) or unique alphanumeric
- Registration Certificate: PDF download (proof of registration)
- Decal: Instructions to affix identifier on aircraft
Piyo: "Do I need to physically mark my aircraft with the registration number?"
Poppo: "Yes. CASA requires the registration number to be marked on your aircraftโusually on the fuselage or rear landing gear. It's a small decal, but it's legally required and checked during audits."
Step 6: Mark Your Aircraft
Marking requirements:- Decal size: Minimum 5 cm height
- Location: Fuselage, rear arm, or landing gear (visible from distance)
- Color: Black or white (contrasting with aircraft color)
- Example: A small sticker reading "AU-RPA-0001234"
- Clean surface (remove dust, grease)
- Peel backing from decal
- Affix to aircraft
- Press firmly (10 seconds)
- Allow adhesive to cure (24 hours)
Registration Costs & Timeline
| Aspect | Details |
|---|---|
| Registration Fee | Free (CASA-funded) |
| Decal Printing | $10โ$30 (self-print or CASA supply) |
| Total Cost | $0โ$30 |
| Timeline to Registration | 24 hours (online application) |
| Validity Period | 5 years (matches ReOC validity) |
Managing Multiple Aircraft
If you operate 5+ RPA, register each separately:
Registration Table Example:| Aircraft | Model | Serial | MTOM | Reg # | Status |
|---|---|---|---|---|---|
| Survey-1 | Matrice 300 | SN-2024-0451 | 45 kg | AU-RPA-0001 | Active |
| Survey-2 | Matrice 300 | SN-2024-0452 | 45 kg | AU-RPA-0002 | Active |
| Backup | Mavic 3 | SN-2023-1240 | 1.5 kg | AU-RPA-0003 | Active |
What Happens Post-Registration
Ongoing Compliance
Your registered aircraft is now tracked by CASA:
- Incident reporting โ If registered RPA involved in accident, CASA notifies you to submit incident report (form CA-4)
- Maintenance tracking โ Auditors cross-reference registered aircraft with your logbooks
- Insurance verification โ Insurers use registration number for claim handling
- Renewal โ ReOC renewal automatically renews aircraft registration (no separate renewal needed)
Updating Registration
If you change aircraft details:
Change: Payload added (lidar, radiometric camera)- Action: Recalculate MTOM; update registry
- Timeline: Within 2 weeks of modification
- Action: Deregister (delete from registry)
- Timeline: Within 30 days
- Action: Notify CASA; may require re-inspection before resuming ops
- Timeline: Immediate notification
CASA Audits & Registration Verification
During CASA audit, auditors verify:
- โ Aircraft are registered (check registry)
- โ Decals are visible & legible
- โ Maintenance records match registered aircraft
- โ Registration data (MTOM, serial) matches aircraft
MmowW Integration: Streamlined Aircraft Registration

Cost: A$8.50/drone/month. Eliminates spreadsheet management of aircraft registrations.FAQ
Q: What if I can't find my aircraft's serial number?A: Check: battery housing, motor labels, fuselage engraving, purchase invoice, or manufacturer's database. If truly lost, contact manufacturer for verification, then register with verification letter from them.
Q: Can I register an aircraft I don't own yet?A: No. Register only aircraft you currently operate. Once delivered, register within 7 days.
Q: If I operate in multiple states (NSW, VIC, QLD), do I register with each state's aviation authority?A: No. CASA's national RPA Register covers all states. Single registration, nationwide authority.
Q: What if I lose my registration certificate?A: Re-download from CASA's RPA Register portal. You can access it anytime with your ReOC login.
Q: Do hobby RPA flyers need to register?A: No. Only ReOC holders (commercial) must register. Hobby operators are exempt.
Q: What if I sell my RPA?A: The new owner (if commercial, holding ReOC) must deregister your RPA and register it under their name. You must notify CASA of sale within 30 days.
Q: Can CASA see my registration details?A: Yes, fully. Public can't access your registry (privacy protection). CASA uses it for audits & incident investigation.
Common Mistakes to Avoid
| Mistake | Consequence | Prevention |
|---|---|---|
| No registration despite ReOC | Compliance violation; potential ReOC suspension | Register immediately upon purchasing RPA |
| Wrong MTOM listed | Insurance claim disputes; regulatory breach | Weigh aircraft + batteries; calculate honestly |
| Decal not affixed | Audit violation; grounding order | Install decal within 7 days of registration |
| Registration expired (not renewed) | Aircraft out of compliance | Renew ReOC; registration auto-renews |
| Aircraft sold, still registered under your name | Liability risk (old owner traced to you) | Deregister within 30 days of sale |
The Bottom Line
Registering your drone with CASA is a 5-minute online process, free, and legally required. Forgetting or skipping registration is a compliance violation that costs you in audits. Use CASA's RPA Register, affix your decal, and you're covered.
