Marine Infrastructure on the Gold Coast

Maintenance & Upgrades for Civil Infrastructure


Marine infrastructure faces some of the harshest conditions — and if it’s not built right, it won’t last. That’s where On Demand Barges comes in. We deliver specialised marine civil works on the Gold Coast, the Sunshine Coast, in Brisbane, Northern NSW, and regional QLD.


Our team helps clients build durable, compliant structures like seawalls, bridges, retaining systems, and erosion control solutions.


From site preparation and foundation work to final installation, our team manages it all. Whether you're protecting a waterfront development or improving marine access, we offer practical solutions tailored to your needs.
