Visitors (including Australians) flying to the United States should be aware that electronic devices such as phones, laptops, and tablets may be subject to search by U.S. Customs and Border Protection (CBP) officers upon entry. Understanding the legal framework and your rights can help you prepare and reduce the risk of surprises at the border.
CBP’s Authority to Search Electronic Devices
CBP officers are legally allowed to search electronic devices at the U.S. border without a warrant or individualized suspicion. This authority has been upheld under the “border search exception” to the Fourth Amendment. According to the American Civil Liberties Union (ACLU), travelers who refuse to comply may face significant consequences:
- U.S. citizens cannot be denied entry, but their devices may be seized and delays are likely
- Non-citizens (including Australians) may be denied entry if they refuse to unlock or hand over devices

Types of Searches Conducted
CBP classifies searches into two categories:
- Basic Search: A manual examination of a device, such as scrolling through content without external tools
- Advanced Search: Involves connecting the device to external equipment to extract, copy, or analyze data. Requires supervisory approval and is conducted based on reasonable suspicion or national security concerns
CBP policy restricts officers from accessing cloud-based data. They are only permitted to review data stored locally on the device.

Legal Implications for Australian Travelers
The implications vary depending on your immigration status:
- Visa Waiver Program entrants: Australians using ESTA can be denied entry if they decline to unlock devices
- Tourist and work visa holders: Similar risks apply. Denial of entry is possible if CBP deems the traveler uncooperative
- Permanent residents and citizens: May face device confiscation and long delays, but cannot be denied entry
Legal experts recommend that all travelers comply with CBP instructions at the border, even if they disagree with the process.
How to Protect Your Data When Flying to the U.S.
To reduce your risk and protect your privacy, consider taking the following precautions:
- Minimize stored data: Travel with a clean device or remove non-essential files
- Back up important data: Securely store data in the cloud or an external drive before departure
- Use encryption: Enable full-disk encryption and turn off devices to protect encryption keys
- Set strong passwords: Avoid using biometric unlock options like Face ID or fingerprint if you want to retain control over access
- Understand the consequences: If you refuse to unlock your device, be prepared for the possibility of denial of entry or device seizure

Comparisons with Australian Border Force Practices
Australia’s Border Force (ABF) also has powers to search electronic devices, and has done so extensively in recent years. Between 2021 and 2024, ABF conducted nearly 10,000 searches of travelers’ devices. While providing a password is not mandatory under Australian law, refusal can result in devices being retained for forensic analysis.

Electronic device searches at the U.S. border are a reality for travelers, including Australians. Being informed and taking proactive steps can help protect your data while avoiding entry issues. Whether you’re entering under the Visa Waiver Program or holding a work visa, compliance and preparation are key to a smooth border experience.
