Brand anthem and audio logo for a2 Milk's new brand platform, launched with the Tough Tummies campaign.

The Challenge

Launching a new brand platform with music that could travel — not just for the campaign, but as a long-term sonic anchor for the brand.

Brand-level
Express the Tough Tummies platform in sound. Warm, grounded, and distinctly Australian, without tipping into sentimentality.

Creative
Connect authentically with the line Only A2 Will Do — building an audio logo that works as a standalone brand signature, not just a campaign endtag

Operational
Deliver assets modular enough to deploy across TV, OOH, social, and programmatic without losing emotional consistency across lengths.

The Solution

A sonic identity designed to grow with the brand — an audio logo and anthem built for consistency at scale, not just campaign by campaign.

The Approach

The Foundation
The Tough Tummies campaign, celebrating the everyday. A celebration of something simple.

Creative direction
Warm and organic, without being earnest. Distinctly Australian in character: real, unpretentious, human.

Distinctive elements

  • Acoustic-led instrumentation — grounded and human, no clinical polish

  • Audio logo anchored to Only A2 Will Do — sung, simple, built to stick



The System

Audio Logo — consistent mnemonic for sign-off and attribution
Hero Brand Theme — master composition with flexible edit architecture

Building Salience

A sonic platform built to compound over time

The brand anthem and audio logo gave the Tough Tummies platform a coherent sonic presence from launch — consistent across TV, OOH, social, and programmatic.

  • Built-in attribution: The audio logo's connection to Only A2 Will Do creates an earworm that builds brand recognition with every impression, even without visual cues.

  • Reduced production friction: Modular asset architecture gave BMF and the a2 Milk team the tools to move efficiently across formats without recreating from scratch.

  • Consistent emotional territory: Acoustic-led, warm, and distinctly Australian character held across every format length and placement.
