Oversized Item Delivery Options

Since oversized items require special handling, we may need to provide a custom freight quote for your order and will contact you with an updated shipping rate.

Available options include:

✔ Delivery to your closest depot for pickup - default method
✔ Direct delivery - requires forklift on site
✔ Direct delivery with tailgate lift truck (extra fees apply)
✔ Forklift loading at our warehouse (no extra charge if you arrange your own freight)
✔ Direct truck delivery (available in Victoria)

Important Notes:

• Shipping costs vary by location and method
• Because of the forklift requirement, delivery to the nearest depot is the default option and will be the method used unless you contact us to request otherwise.
• Bulky and oversized items cannot be delivered to a PO Box - please provide a physical street address for delivery.

Business Delivery:

• Business delivery is available for commercial customers only
• If you select business delivery and your products are bulky, it is your responsibility to ensure you have appropriate equipment (including forklifts) to unload products from the delivery truck
• If you select business delivery and you are not a business, you risk your product not being delivered and may incur additional fees to retrieve your order
• Business delivery customers must provide a valid business address and contact information
• Additional fees may apply for failed delivery attempts due to lack of appropriate unloading equipment

Let us know your preference, and we'll arrange the best solution for you!

Important Note on Availability & Shipping

Our warehouse serves as our office and logistics centre rather than a retail showroom. Because we ship from multiple locations and manage high-turnover stock, not all items are available for immediate pickup.

Lead Times:

• In-Stock Items: Usually ready for dispatch the same day.
• Supplier-Dependent Items: Usually take 2–8 weeks to arrive, depending on supplier availability. Products from Adloheat may take 4–12 weeks depending on the order—they are custom made to order in Pakenham, VIC.

While we strive for fast delivery, some timelines are subject to supplier availability and are beyond our control. We appreciate your patience as we source the best quality gear for your project.
