Creative Melbourne solution to graffiti vandalism a game-changer
A Melbourne innovation could soon become a powerful weapon in the war against illegal graffiti – recycled plastic panels that frustrate vandals by making their “artwork” illegible.
Developed by Australian security expert Luke Percy-Dove, the panels – known as TagShield – are designed to be retro-fitted to noise barriers, bridges, tunnels and other infrastructure, dramatically reducing costly maintenance.
Patented in 158 countries, each one square metre panel features a complex network of shapes and channels that renders graffiti unreadable, along with a specially engineered polymer that makes the paint run – making it difficult to create graffiti in the first place.
“We believe these panels are a game-changer on many fronts and could transform the way graffiti globally is managed along major roads and railway corridors,” said Mr Percy-Dove, the director of Melbourne-based Matryx Consulting.
“Traditional graffiti removal is an expensive, never-ending cycle – removing it simply provides a fresh canvas for more vandalism, which costs taxpayers millions of dollars a year.
“We know that some sites have to be repainted weekly, which means the focus needs to change from simply managing the problem to actively discouraging it.
“Our approach means that graffiti vandals won’t be able to see the results of their dubious efforts, let alone any ‘tags’, because it will be hidden within the patterns of the panels – making it a pointless exercise for them.
“While we’re trialing the panels early 2026 in selected sites with the Victorian Government, our vision is to roll out this initiative across all Australian states within the next 12 months.”
Mr Percy-Dove said the panels, now market-ready, were the result of more than two years of laboratory testing – and dozens of prototypes.
“Additionally, in Australia, where less than 15 per cent of plastic is diverted from landfill, we’re repurposing it into a valuable product.”
As a national security consultancy, Matryx Consulting has worked with scores of governments at all levels and seen firsthand the amount of energy and money that is spent on graffiti management.
Mr Percy-Dove estimated the panels, which have a projected lifespan of 30 years, would pay for themselves when compared to the current cost of just four to eight rounds of graffiti removal.
“We know from our own discussions with graffiti removal contractors that it can cost up to $600 a year per square metre to manage graffiti. Because of the sheer scale of the problem, that becomes an enormous burden on taxpayers and the owners of infrastructure.
“We believe the TagShield panels, which will also be fully recyclable at the end of their lifespan, will generate significant cost savings.”
