Big ideas, and the technology to make them work.
Tonic The Agency is the Sydney marketing and technology agency behind work for LG, ASUS, Microsoft and Sonic Healthcare. Unlike most agencies, our strategists, creatives and developers work as one in-house team, from the first idea to the platform it runs on.

What we do
Not a creative agency. Not a dev shop. Both.
Most brands brief one agency for the idea and another to build it, then spend months managing the gap. At Tonic, strategy, creative and development sit in one team, so the campaign, the website and the automation behind it are planned together.
It’s how we deliver for some of Australia’s best-known brands: Adobe Experience Manager for LG, launches for ASUS and Fujifilm, direct mail for Microsoft and Oracle NetSuite, and apps that deliver test results for Sonic Healthcare.
And it’s why clients stay. Our average client relationship is more than eight years, and Sydney Festival has worked with us for over 15.
