What does Sandbox mean and why Sandbox Media?


In the innovation world, the Strategic sandbox is the first part of the innovation process. You start with a challenge; conduct some activities that provide insight, understanding, and ideas for solutions, then bring all the knowledge together towards a strategy.


‘Sandbox’ started out for the military as exactly that. A table-top box of sand on which military plans and strategy could be demonstrated. A place for trying out various approaches and solutions to problems so that they can agree on the best plan and execute that plan with collaboration and precision.


Open-World Game in an online gaming context. With an Open-World Game, the world is your oyster. That means you can do whatever you please. You can go where you want or build what you want. It’s your SANDBOX, you can play in it however you like.

Let’s open a conversation about how WE can work with YOU. Everyone likes to work differently and has completely different needs.


Media Buying with Sandbox

When you strip away the industry speak and agency sales pitches, what’s left is the stuff that matters – the work and the results. Our work builds brands, creates new customers and sells. It is ultimately why our clients choose to partner with us.

At Sandbox we don’t deliver one-size-fits-all plans. Sandbox are different. We are independent and channel-agnostic so we plan and buy media in accordance with the campaign strategy and the behaviours of the SPECIFIC audiences we are targeting for our clients. Our independence means we buy what is right for our clients, always.

With over 165 years of combined experience in both media sales and buying in Australia we are about as connected as we can be in this tight knit industry. These close working relationships do not happen overnight. We have developed and cultivated our media relationships over many years. When you partner with Sandbox you know you are partnering with the who’s who of the Australian and New Zealand Media industry, something that’s meaningful for both your campaign spend and results.
