A Wall, A Crisis
One of the hardest things in advertising is making the invisible visible. Especially when the issue is a problem that exists right in front of society’s eyes and yet continues unnoticed. Child homelessness in Australia is exactly that kind of problem. There are numbers, reports, and data, but these figures often fail to create an emotional response. People read them, but they do not feel them.
This campaign, created by We Are Mobilise and developed with Droga5, targets exactly that disconnect. But it does so not through large productions, dramatic films, or heavy storytelling. It does it through something extremely simple, almost ordinary: children’s height marks.
Displacing a Familiar Symbol
Marks drawn on walls to measure children’s height are an almost universal image. They represent something tied to home: warmth, safety, and a personal memory. Tracking a child’s growth is a small but meaningful ritual that makes them feel that they belong somewhere.
This campaign takes that exact symbol and removes it from where it belongs.
Appearing on walls and open surfaces in public spaces across Sydney and Melbourne, these height marks create an image that feels familiar at first glance, but also deeply unsettling. Because these marks are not at home. They are in the street. In other words, outside the place where they are supposed to be.
This displacement becomes the campaign’s strongest storytelling device.
Not Data, but Experience
At the heart of the campaign is an important fact: approximately 28,948 children and parents in Australia do not have stable housing. But instead of stating this figure directly, the campaign chooses to make it felt.
Each mark is:
- based on the average heights of children between ages 4 and 12
- representative of real growth intervals
- a physically measurable reality
This transforms the issue from an abstract number into a physical experience. When people stand next to these marks, they begin to imagine not just a statistic, but the life of a child.
Invisible Homelessness
When people hear the word homelessness, most imagine individuals living visibly on the street. But the real situation is much more complex. The campaign draws special attention to this point.
Because many children:
- live in cars
- stay in temporary shelters
- move constantly between different homes
So even if they are not visibly on the street, they are still living a homeless life.
This “invisible homelessness” is one of the most critical dimensions of the issue. The campaign aims to make that invisibility visible.
The Message as Street Art
The strength of this work lies in the fact that it does not look like advertising. These marks are:
- not a billboard
- not a poster
- not a campaign surface
They appear as if they are simply part of the street.
This changes the relationship with the viewer. People do not feel that they are encountering an advertisement. They feel that they have noticed something.
That moment of realization is much more powerful than a conventional advertising effect.
Minimalism and Impact
One of the most striking parts of the campaign is what it does not do.
- there is no big-budget production
- there are no complex visual effects
- there are no long narratives
Instead, there are:
- simple lines
- a clear message
- the right placement
This simplicity increases the power of the message. Because there is nothing distracting the audience. The viewer is left directly alone with the issue.
From Physical to Digital
The campaign does not remain limited to physical space. QR codes placed in the installations direct viewers straight to the donation page. In addition, digital out-of-home applications help the campaign reach wider audiences.
This is important. Because awareness alone is not enough. It needs to be turned into action.
The Voldi Creative Perspective
At Voldi Creative, we see this project as an especially powerful example of “emotion design.”
What is happening here is:
- not explaining a problem
- but triggering a feeling
The fact that such a simple symbol as a child’s height mark can become such a powerful narrative shows how accurately the idea has been built.
This campaign reminds us of something important:
The most effective works are not the most complex ones;
they are the ones that capture the issue from exactly the right place.
This work by We Are Mobilise and Droga5 shows that street art can function not only as an aesthetic tool, but also as a social one. The campaign makes an invisible problem like child homelessness visible through an extremely simple but powerful method.
And perhaps the most striking part is this:
A line that normally measures a child’s growth
here represents absence.
That contradiction is the campaign’s strongest sentence.
