Grant Day James is more than an ad agency. It’s a philosophy – the concept of bringing together talented people as one organic collective that does great work and gets the best results for clients who value a highly personalised service. Clients like working with us because even when the heat is on, we get the job done with a can-do attitude and a liberal dose of good humour. If you want an imaginative approach to your work and you like the look of the people in our team, then we’re probably the one for you.

Who are GDJ?

About the G, the D and the J.

Cathy Grant, Ben Day and Peter James met in advertising in the early 1990s. Cath was a budding client service talent and Ben and Pete were the creatives. Not much has changed really, except lots of experience since forming Grant Day James in 1996. The great thing is that each Director continues to work in the business and brings different skills to the table.


Sometimes it takes a shift of a few degrees to communicate things from a different point of view. In advertising, that could mean developing a new strapline. Or inventing a new visual approach. Or overhauling the words. Or maybe it’s coming up with a completely new direction that talks about your business in a way that opens eyes and opens minds.

We’re not into awards so much, we’re into making ads that work.

Client: Premier’s Active April

Premier’s Active April

Premier’s Active April is all about getting Victorians more active, more often and features a fantastic program that encourages this activity during the month of April. In 2014, more than 90,000 Victorians participated. Check out the spectrum of work we did for this great program.


We’re lucky to have such a clever team of people at GDJ. The relatively flat structure here and the modest size of our operation means that our people develop a rich array of talents. That makes them tremendous assets for our clients who rely on their skills to bring communications work to life. We’ve got an enthusiastic account service team that works with you closely. And we’ve got writers, art directors and technical people who can make anything sing – from a tiny press ad to a magazine, a website, an online strategy, a radio or TV ad, an outdoor billboard… you name it.

We get that budgets are important. We get that time is too – you don’t want to spend five meetings briefing an agency when they should get it first time. We also get that you want solutions – plural. More often than not, we’ll provide ones that you haven’t considered. And while we’re on the subject of solutions, we’ll also go the extra yard to get you out of a tight spot and deliver what you need on time, on budget and on deadline.

Client: Zoos Victoria

Zoos Victoria

Zoos Victoria is great fun to work with and we hope it shows. We enjoy creating vibrant, considered, energetic work for a true Victorian institution.

Client: Strathcona

One of our “foundation” clients, Strathcona is a wonderful independent girls' school in Melbourne. The sense of community and family is an important part of their message and we enjoy a close working relationship with their team to develop a range of communication materials that tell this story well.


Good work comes from strong relationships. So let's build one.
