ADT Security operates 24/7 professionally monitored alarm systems and video surveillance across Australia, with mobile app alerts, optional home automation and nationwide response networks. Whether you've relocated, found a cheaper alternative, downsized your property, or simply no longer need round-the-clock monitoring, you'll discover that cancelling requires direct contact-ADT Australia does not permit online termination.
The critical challenge you face is this: ADT Security contracts typically lock you into 36-month minimum terms with early termination fees and equipment clauses that can escalate your exit cost significantly. At Yafee, we've analysed thousands of Australian security contracts, and understanding your legal rights before you call ADT makes the difference between a smooth exit and unexpected charges.
Your reasons for cancellation fall into three distinct categories. Cost concerns lead most people-finding a cheaper monitored service, switching to DIY systems, or discovering competitors offer better value. Life changes come second: you may have relocated interstate, downsized your home, or no longer require 24/7 monitoring after a major life event. Service frustration ranks third: slow police response times, billing disputes, or inadequate customer support push customers toward competitors.
Before you proceed with cancellation, pause and assess whether your frustration stems from price alone or from genuine service failure. If cost is the only issue, Yafee recommends negotiating a rate reduction with ADT first-one phone call often secures a lower monthly fee faster than switching providers entirely.
ADT advertises basic alarm monitoring from approximately AUD $32.90 per month, but your actual cost depends on your package tier, equipment arrangement, installation fees, and any video or automation add-ons you've selected.
| Package type | Monthly cost (AUD) | Equipment and setup |
|---|---|---|
| Basic alarm monitoring | From $32.90 | Equipment hire or purchase; installation varies |
| Video monitoring add-on | +$9 to $30 | Additional camera costs; cloud storage fees |
| Combined alarm and video | $30 to $90 | Full system install; ongoing equipment hire |
| Home automation bundle | $50 to $120 | Smart device integration; premium monitoring |
| Premium response package | $80 to $150 | Priority dispatch; advanced automation |
Australia's legal framework provides you with specific protections when terminating monitored security contracts, and knowing these rights strengthens your negotiating position before you contact ADT.
Under the Australian Consumer Law (ACL), if you signed your ADT Security contract as a direct result of unsolicited contact-such as door-to-door sales, cold calls, or telemarketing-you hold a 10 business day cooling-off period from the contract date. This period permits you to terminate the agreement without penalty, regardless of any minimum-term clause.
To exercise this right, you must send written notice to ADT Security within 10 business days. Address your cancellation letter to the mailing address provided in the final section of this guide and retain a copy for your records. ADT must return any deposits and equipment within 14 days of receiving your notice.
Your legal position: Cooling-off rights apply only to "unsolicited consumer agreements". If you approached ADT directly, visited their office, or responded to advertising you sought out yourself, this right does not apply. Nevertheless, other protections remain available under the ACL if ADT breached its obligations to you.
The ACL also protects you against unfair contract terms-clauses that create a significant imbalance in your and ADT's rights and obligations. If your contract includes a penalty clause charging you thousands of dollars for early termination despite ADT's minimal loss, a court may declare that term unenforceable.
Furthermore, if ADT refuses to accept cancellation or demands an unreasonable early termination fee (for example, charging your full remaining contract value when they could immediately re-lease the equipment), you can lodge a complaint with the Australian Competition and Consumer Commission (ACCC). The ACCC enforces the ACL and investigates breaches of consumer protection rules.
In addition to federal consumer law, your state may impose licensing requirements on security companies. Some states permit you to cancel security contracts if the licensed operator fails to comply with state security laws. Check your state's relevant authority-such as the NSW Security Industry Regulator or equivalent-to confirm whether ADT's conduct breaches local licensing standards.
ADT Security requires you to initiate cancellation through direct contact; online self-service termination is not available on their platform.
Calling ADT remains the fastest cancellation method. Ring the ADT customer service team on 131 ADT (131 238) during business hours. Have your account number, customer name, and property address ready. Inform the operator you wish to cancel your alarm monitoring service, state your intended termination date, and ask for written confirmation by email or post.
During the call, the operator may offer you a rate discount or service upgrade to retain your business. Yafee recommends deciding in advance whether you would accept a reduced rate-if not, remain firm and request immediate cancellation rather than extending the conversation.
If you prefer a documented trail, send a formal cancellation letter via Australia Post to ADT's registered mailing address. This method ensures you have proof of your cancellation request and the exact date ADT received your notice. Write your account number, customer name, and property address clearly on your letter, state your intended cancellation date, and request written confirmation.
Send your letter to the address listed in the final section below. Use registered mail with tracking so you can confirm delivery. ADT should acknowledge receipt within 5 business days; if they do not, follow up with a phone call to 131 ADT and reference your postal date.
Follow these precise steps to terminate your ADT Security contract with minimal friction and maximum documentation.
Early termination fees are the primary financial barrier to cancelling ADT Security before your minimum term expires, and understanding how they are calculated puts you in control.
ADT's standard early termination fee multiplies your remaining contract months by your monthly service fee. For example, if you have 18 months remaining on a $35-per-month plan, your termination fee is typically $630 (18 × $35). However, your contract may include alternative calculations: some contracts cap the fee at a maximum (for example, three months' service), while others reduce the fee if you've served a portion of the original term.
Furthermore, ADT may charge separate equipment fees if you own hardware outright and choose not to return it, or if you damage the system during your tenancy. Read your contract carefully and ask ADT's cancellation specialist to itemise all charges before you confirm cancellation.
ADT has discretion to reduce or waive early termination fees in certain circumstances. If you cite service failures, breach of monitoring standards, or relocation due to circumstances beyond your control (such as a landlord's decision to terminate your lease), the cancellation specialist may escalate your case to a manager who can offer a partial fee waiver.
At Yafee, we recommend framing your request as a hardship negotiation rather than a complaint: "I'm relocating and my new property is outside ADT's coverage area. Would you consider reducing the termination fee given my circumstances?" This approach is more likely to succeed than demanding the fee be cancelled outright.
If ADT owes you a refund-for instance, because you paid in advance or your deposit applies to your final bill-the company must process the refund within 14 days of your cancellation date. Request the refund method (direct bank transfer, cheque, or credit card reversal) when you call 131 ADT.
If the refund does not arrive within 14 days, contact ADT again with your cancellation confirmation letter and request an immediate trace. If ADT fails to refund within a further 7 days, lodge a complaint with the ACCC or your state's relevant consumer authority.
Cancelling an ADT contract is straightforward if you avoid these frequent errors that delay resolution or cost you unnecessary money.
Many customers waste time searching ADT's website for a "cancel account" button or self-service portal. ADT Australia does not offer online cancellation. You must call 131 ADT or post a written letter. Accepting this restriction upfront saves you frustration and accelerates your cancellation.
When you call 131 ADT without your account number, contract details, or monthly fee amount, the operator will place you on hold while they look up your records. Furthermore, without your contract in hand, you cannot challenge an incorrect termination fee calculation on the spot. Gather all documentation before you dial.
ADT's operators are trained to retain customers by offering rate discounts. If you accept a verbal discount without requesting written confirmation and a revised contract, ADT may not honour the new rate. Always demand written confirmation by email before you cancel the call, or decline the offer and proceed with termination.
If your contract states that ADT owns the equipment, removing or disconnecting it before formal collection may expose you to damage charges or breach-of-contract claims. Wait for ADT to confirm collection or confirm in writing that you may disconnect it. Photograph the system's condition beforehand to protect yourself against false damage claims.
Many customers assume their final bill is correct and do not review it. However, ADT may apply incorrect termination fees, fail to prorate your final monitoring charges, or add mystery charges. Review your final bill within 10 days and dispute any errors immediately. After 30 days, ADT may refuse to adjust charges.
Once your ADT contract terminates, take these steps to ensure a clean break and to protect your home's security during any transition period.
Do not let your cancellation date arrive without a replacement system in place. Research alternative monitored security providers, DIY systems, or local security firms at least 4 weeks before your ADT cancellation date. This prevents a gap in your home's protection and allows you to request a staggered transition where the new system activates on the same day ADT deactivates.
After you call 131 ADT, send a follow-up email to ADT's customer service address (included in the contact section below) with the subject line: "Cancellation confirmation request-Account [your number], effective [date]." This creates a written record of your cancellation request and ensures ADT cannot later claim they did not receive it.
Monitor your bank account for the promised refund within 14 days. If ADT deducts a surprise charge or fails to refund in that timeframe, contact your bank immediately and lodge a dispute. Furthermore, monitor your original payment method (credit card or bank account) for 30 days after cancellation to ensure no residual charges appear.
Some home or landlord insurance policies require proof that your alarm system is active or officially deactivated. Ask ADT in writing to provide a cancellation confirmation letter stating the system was deactivated on your cancellation date. Keep this letter for your insurance records.
If cost is your cancellation driver, compare ADT's pricing against competing monitored security providers to confirm you'll save money by switching.
| Provider | Basic monitoring (monthly, AUD) | Equipment costs | Contract term |
|---|---|---|---|
| ADT Security | $32.90 | Hire or purchase; varies | 36 months typical |
| Burgess Australia | $25 to $40 | Equipment hire or purchase | 24 to 36 months |
| SecureNet | $20 to $35 | Lease or own | 12 to 24 months |
| DIY systems (Eufy, Abode) | $10 to $20 monitoring + app | One-time hardware ($200-$600) | Month-to-month or no contract |
| Local independent providers | $20 to $45 | Varies by provider | Negotiable |
If you choose a DIY system such as Eufy or Abode, calculate the total cost of hardware plus 12 months of monitoring and compare it to ADT's termination fee plus 12 months of remaining service. In many cases, switching to a cheaper provider and paying ADT's early termination fee is still more cost-effective over two years than continuing with ADT.
Use this checklist to ensure you've completed every critical step before you call 131 ADT.
If ADT's customer service team refuses to accept your cancellation or demands an unreasonable termination fee, escalate your complaint to the ACCC and your state consumer authority.
The Australian Competition and Consumer Commission (ACCC) enforces the Australian Consumer Law and investigates complaints about unfair contract terms, misrepresentation, and breach of consumer guarantees. If ADT refuses to cancel despite your meeting all contractual obligations, or if they demand a termination fee that appears grossly disproportionate to their actual loss, file a complaint online at accc.gov.au.
The ACCC will contact ADT on your behalf and request a response. In many cases, the threat of ACCC involvement prompts ADT to reconsider their position and negotiate a settlement. Provide the ACCC with copies of your contract, cancellation request, ADT's refusal, and any evidence of service failures or breach.
In addition to the ACCC, each Australian state operates its own consumer protection office. NSW has the NSW Department of Fair Trading, Victoria has Consumer Affairs Victoria, and so on. These agencies investigate complaints about contract disputes and may offer mediation services to resolve your dispute with ADT without court action.
Furthermore, in some states, security systems fall under additional licensing and regulatory frameworks. If ADT breaches state-specific security regulations, your state regulator may have enforcement powers that the ACCC does not possess.
If your termination fee dispute is below the small claims threshold in your state (typically $10,000 to $20,000 depending on jurisdiction), you can file a claim in the local court or relevant tribunal. Yafee recommends obtaining legal advice before pursuing this option, as court costs may exceed the fee in dispute. However, if ADT's termination fee is clearly unfair under the ACL, a court is likely to award in your favour and may order ADT to cover your legal costs.
Use these official contact details when you cancel your ADT Security contract.
Call ADT customer service on 131 ADT (131 238) during business hours. Have your account number and property address ready. Request to speak with a cancellation specialist and confirm your cancellation date in writing by email before ending the call.
Send your written cancellation letter via registered Australia Post to:
ADT Security Pty Ltd
Customer Service Department
PO Box 6007
Alexandria NSW 2015
Include your account number, customer name, property address, and intended cancellation date in your letter. Request written confirmation of cancellation in response. Use registered mail with tracking to confirm ADT receives your letter.
If you receive no response to your postal letter within 7 business days, email ADT's customer service team (address available via 131 ADT) with a copy of your cancellation letter and the registered mail tracking number. Demand a response within 3 business days.
Cancelling an ADT Security contract demands patience and documentation, but the process is straightforward if you know your rights and follow a methodical approach. The Australian Consumer Law protects you against unfair contract terms and unsolicited agreements, and the ACCC enforces these protections on your behalf if ADT refuses to cooperate.
Before you cancel, confirm your contract's termination fee, arrange alternative security coverage, and decide whether negotiating a rate reduction might serve you better than a full exit. During the cancellation call, remain calm, request written confirmation, and do not agree to verbal offers without email corroboration.
After termination, review your final bill within 10 days, confirm your refund arrives within 14 days, and monitor your account for residual charges. If ADT delays, disputes, or refuses cancellation, escalate to the ACCC and your state consumer authority without hesitation.
Yafee has helped thousands of Australian consumers navigate security contract cancellations by grounding their decisions in law and practical procedure. Use the checklist above, follow the five-step cancellation process, and document every communication. Your cancellation should complete within 4 to 6 weeks from your initial call to 131 ADT. If it does not, you have clear grounds to escalate your complaint to the regulators who will enforce your consumer rights on your behalf.
