About
Second generation, and still answering the phone.
Precision in Every Line
Who we are
One family, one workshop, and the crews to carry a whole network.
Southern Highway started twenty-five years ago in Debbie and Rick Gloster's backyard in Geelong. After years working for VicRoads and Sprayline, Rick saw a gap in the market for quality local line marking — and started filling it, one car park at a time, with one offsider.
The second generation runs it now: Katie and Wayne Robertson bought the business from Katie's parents three years ago. Today it's a team of 25 marking from Geelong to the South Australian border — with the fleet, the crews and the signage manufacturing still in-house, which is what lets one company carry a council's whole programme and stay accountable for it.

What we hold to
Three things every job gets measured against.
Not slogans. These are the terms councils and Tier 1 contractors hold us to, and the terms we hold our own crews to.
Precision
Every line straight, every spec met. Set out once, applied right.
Safety first
Our crews, the client's crews, and every driver who follows behind.
Local and accountable
Geelong workshop, Western Victoria roads. We answer the phone.
Where we work
One workshop, 32 regions.
Five crews run out of Geelong and one out of Horsham, rather than being subcontracted region by region. Highways, arterials and council networks — and the car parks that come with them.
