Understanding Self Bunded Tanks
Before comparing Smart Cubes and Duro Cubes, it’s important to understand what makes them both safe and compliant: their self bunded construction. A self bunded tank features a double-wall design. The inner tank stores the fuel, while the outer wall acts as a containment vessel. This design provides several benefits:
- Environmental Protection: In the event of a leak, the outer bund contains the fuel, preventing spills from contaminating soil or waterways.
- Regulatory Compliance: Australian standards for fuel storage are strict, and self bunded tanks meet these requirements, ensuring your operations are compliant.
- Durability: The double-wall design is built to withstand harsh environmental conditions, extending the lifespan of the tank.
Both Smart Cubes and Duro Cubes utilise this self bunded design, offering reliability and safety. However, the key differences lie in mobility, internal features and the operational contexts they are intended for.
Smart Cubes: The Ideal Stationary Fuel Storage Solution
Smart Cubes are designed primarily for stationary use. They are perfect for sites where the fuel will be stored in one location and transported infrequently, if at all. Here are the standout features of Smart Cubes:
- Capacity Range: Smart Cubes are available in sizes from 250 litres up to 8,000 litres, making them suitable for a wide range of operations. Whether you need a small tank for machinery on a farm or a larger tank for construction equipment, there’s a Smart Cube to fit your requirements.
- Safety and Compliance: Each Smart Cube is equipped with a calibrated dipstick, safety signage and provisions for fast-fill systems. The self bunded design ensures 110% containment of the tank’s capacity, giving operators peace of mind.
- Forklift Pockets: While primarily stationary, Smart Cubes include forklift pockets, allowing the tank to be repositioned or relocated when empty. This feature is especially useful for maintenance or rearranging site layouts.
- Applications: Smart Cubes are ideal for fixed operations in agriculture, construction, mining or any industry where fuel storage doesn’t require frequent transport. They provide a reliable, long-term solution without the added costs of transportability features.
In essence, Smart Cubes are cost-effective, practical and built for stability. For businesses with a consistent, fixed fuel storage requirement, they are a dependable choice.

Duro Cubes: Fuel Storage That Moves With Your Operations
Duro Cubes, on the other hand, are designed for transportability. Unlike Smart Cubes, these tanks are engineered to be moved while full, offering operational flexibility for businesses that operate across multiple sites. Key features include:
- Mobility: The ability to safely transport fuel is what makes Duro Cubes stand out. They are built to endure the rigours of transit without compromising safety or compliance.
- Capacity Range: Duro Cubes come in sizes ranging from 500 litres to 6,000 litres, providing options suitable for small to mid-sized fuel transport operations.
- Internal Baffling: One of the defining features of Duro Cubes is internal baffling, which stabilises the liquid inside the tank during transit. This prevents fuel from sloshing, reduces the risk of spillage and maintains vehicle stability during transport.
- Forklift Pockets: Like Smart Cubes, Duro Cubes also include forklift pockets for easy loading and unloading at various sites.
- Applications: These tanks are ideal for industries that need fuel delivered to remote or temporary sites. Mining, construction and large-scale agricultural operations can benefit from the flexibility of transportable fuel storage.
Duro Cubes provide businesses with versatility. Their design ensures fuel can be transported safely and efficiently, helping operations stay productive even when working in multiple or remote locations.

Key Considerations When Choosing Between Smart Cubes and Duro Cubes
When deciding which tank is best for your business, several factors should be considered:
Mobility Needs
The most obvious difference is mobility. If your operations are primarily fixed and you rarely need to move fuel, a Smart Cube will be more cost-effective and sufficient for your needs. Conversely, if your business requires fuel to be transported to multiple sites, a Duro Cube offers the mobility needed without compromising safety.
Operational Environment
Consider the terrain and conditions where the tank will be used. For stationary setups on a farm, mining site or construction yard, Smart Cubes provide reliable long-term storage. Duro Cubes’ internal baffling and transport-ready design make them a safer choice for operations involving rugged, remote or temporary sites.Â
Capacity Requirements
Assess how much fuel your operations consume and whether your storage needs might change. Smart Cubes offer a slightly wider range of capacities, with options going up to 8,000 litres. Duro Cubes are slightly smaller but are optimised for transport, making them ideal for businesses where moving fuel efficiently is more important than maximum storage capacity.
Cost Implications
Smart Cubes are generally more cost-effective because they are designed for stationary use and do not include transport-specific features like internal baffles. Duro Cubes come with additional design elements for mobility, which may increase initial costs but add value through operational flexibility.
Compliance and Safety
Both Smart and Duro Cubes meet Australian standards for self bunded fuel storage, providing spill containment and durability. Both include essential safety features, such as forklift pockets for handling and safe fast-fill provisions. Choosing either option ensures your business stays compliant while protecting employees and the environment.
