Minimal Google-Compliant Cookie Consent Banner (AU)

This project provides a fully self-contained, dependency-free cookie consent banner designed to meet Google’s consent requirements. It is written in pure HTML, CSS, and JavaScript, and is suitable for use in the Australian market under the Privacy Act and relevant Google policies.

✅ Key Features

• Fully aligned with Google’s EU user consent policy (applicable in Australia if using Google services)
• Platform-independent: no frameworks, no dependencies
• Consent data stored in localStorage
• Compatible with Google Tag Manager (GTM) and gtag.js
• Minimal footprint and no external calls
• Customisable design and logic

⚙️ How It Works

• Displays a simple, accessible cookie banner
• Users can accept or reject cookies
• Consent is applied via the gtag('consent', ...) API
• GTM-compatible dataLayer initialisation included
• Consent is persistent across sessions (via localStorage)

🛠️ Customisation

• Replace styling in the <style> block to match your brand
• Update the privacy policy link (/privacy-policy/)
• Insert your actual GTM container ID where indicated
• Modify consent logic to use cookies instead of localStorage if required

🇦🇺 Legal Context (Australia)

This implementation helps site owners comply with consent requirements when using Google services (such as Google Ads, Google Analytics, or GTM) in Australia. While Australia does not have a direct equivalent to the EU GDPR, Google's policies still apply to Australian publishers and advertisers.

You are responsible for ensuring your own compliance with the Australian Privacy Principles (APPs) and Google's policies.
