Garden Sheds Australia – Steel Outdoor Storage for Your Backyard

Finding the right garden shed for an Australian backyard shouldn't take a whole weekend of research. At SmartStorage.au, we stock steel garden sheds from compact 1.4m slimline units - perfect for apartments, townhouses, and tight side passages - all the way to large 3m+ workshop sheds built for serious outdoor storage. Every shed we sell is weatherproof, lockable, and built to handle Australian conditions: scorching summers, heavy rain, coastal salt air, and everything in between.

What size garden shed do I need?

Size Dimensions Best for
Small Under 2m wide Garden tools, pots, seasonal items, bikes, tight spaces
Medium 2m - 2.5m wide Lawnmower + bikes, garden gear, modest workshop setup
Large 2.5m - 3.5m wide Full tool collection, ride-on mower, workbench
XL / Workshop 3.5m+ wide Workshop, trade storage, bulk outdoor equipment

Do garden sheds come with a floor?

No - steel garden sheds are sold without a floor. Most installations use a concrete slab or compacted pavers as a base. Some of our sheds come with a base frame in which you can lay flooring over a solid concrete or paver base.

Do I need council approval for a garden shed in Australia?

In most Australian states, sheds under 10m² (roughly 3m × 3m) are exempt from council permits in standard residential zones. Larger sheds may need approval - rules differ by state and council. Check with your local council before buying a shed over 3m × 3m.

Common Questions

Do l need a permit for my shed?

Most Australian homes do not need a permit for a garden shed, as long as it’s under 10m² and under 2.4m high. Rules vary by state - NSW and VIC allow small domestic sheds without permits, but coastal and bushfire zones may need approval. Check your state’s council rules to be certain.

How difficult is it to assemble a garden shed?

Most of our sheds are designed for DIY assembly using common household tools. Two people are recommended, and build time is typically 3–6 hours depending on size. We provide step-by-step instructions, pre-drilled panels, and local support if you need a hand during installation.

Larger sheds may require professional help, depending on your skillset and comfort with the DIY build.

How does delivery work for garden sheds?

We offer fast, tracked delivery Australia-wide. Sheds are delivered flat-packed for easy handling (majority from our Melbourne warehouse). You’ll receive delivery updates and instructions. If you specific delivery needs, contact us and we will inform the courier.

What base or flooring do I need for a shed?


A solid, level base is essential for shed stability and weather resistance. Most customers use a concrete slab, but pavers or a timber platform can also work. Some models include or offer a foundation kit for easy anchoring. Need guidance? We can help you choose the right base for your yard.

We also offer a guide here for anchoring & wind resistance.

Do the sheds come with a warranty and Aussie-based support?


Yes - all sheds include a manufacturer warranty and Australian customer support. We’re an Australian family business here to help with product questions, assembly tips, and after-sales support. We want your shed to last for years.
