In Australia, the minimum age for online gambling is 18. Mobile applications of gambling operators implement several layers of control to prevent underage users.

1. App store restrictions

1. Apple App Store

All gambling apps in the App Store are marked with an age rating of 17 + (adults only).
When downloading, an Apple ID with a confirmed age of ≥ 18 is required.

2. Google Play

Content rating "PEGI 18" or "ESRB AO" for gambling.
Limiting downloads through the family library and voluntary Family Link: The parent must approve the installation.

2. Embedded age-gate mechanisms

1. Welcome screen

Before registering, the application displays a warning "Only 18 +" with a date of birth input field.
Without correct entry, continue - neither proceed to registration, nor enter a deposit.

2. System age check

Reading device settings: system date of birth controlled by the user's profile (iOS Screen Time, Android Digital Wellbeing).

3. Mandatory KYC verification

1. ACIP to bid

Before the first deposit and bet, the user downloads a passport or driver's license, the system instantly checks through the DVS-API.
2. Biometrics

Selfie snapshot, reconciliation with photos from the document, NFC reading of the passport (if the device supports).
3. Revalidation

When changing a document or suspicious activity (VPN, abnormal deposits) - repeated KYC request.

4. Geolocation and regional blockages

1. IP geolocation

Determining that the user is in Australia; out of zone - application is unavailable or game partitions are blocked.
2. GPS binding

When using in-play bets, the physical location is checked: only in regions where live bets are allowed.

5. Self-monitoring tools

1. Time and deposit limits

Hard daily/monthly limits on spending and playing time are available in the settings.
2. Self-exclusion (BetStop)

The option of instant self-blocking of the application for a period of 24 hours to life blocking through integration with the national registry.
3. Push-reminders

Automatic notifications when 50%, 75% and 100% loss or time limit is reached.

6. Logs and reports for regulators

1. ACMA reports

Automatic uploading of registration cases to ACMA before KYC and bypass attempts.
2. Embedded analytics

Tracking failures by age, self-exclusion statistics, number of verified accounts.

7. Updates and compliance

1. Regular updates

Timely adaptation of UI/UX to the new requirements of Apple, Google and AUSTRAC.
2. External audits

Annual audits of KYC processes by third-party auditors to confirm compliance with Interactive Gambling Act 2001 and AML/CTF regulations.

Conclusion

Mobile gambling apps in Australia combine age-gate in app stores, built-in date of birth checks, reliable KYC mechanisms, geolocation and self-control tools. This tiered approach ensures strict adherence to the age threshold of 18, protection of vulnerable groups and compliance with legislation and regulatory requirements.
