Once your order is placed, you’ll receive an order confirmation email. This confirms that your order has been received and your payment has been pre-authorised.

We will then verify stock availability. If an item is unavailable or on back-order, we’ll void the pre-authorisation and contact you to discuss alternative options.

If your item is in stock and available for immediate shipment (within 5 business days), we will finalise payment and prepare your order for dispatch.

Order Dispatch & Shipping Notifications

If your order is in stock, it will be shipped within 3 business days of order confirmation.

All orders are shipped via freight only — no pick-up is available. You’ll receive a shipping confirmation email with tracking details within 24 hours of dispatch.

If you haven’t received a shipping notification within 4 business days, please contact us at orders@carparksandroads.com.au.

International Orders

We do ship internationally, but please note:

  • Our products are built for the Australian market (240V electrical systems).
  • They may not meet overseas electrical safety certifications.

We can provide a shipping quote for international orders upon request. If you’re happy with the quote, we’ll send a secure payment link and process your order manually.

Please inspect your items immediately upon delivery.

  • If you notice damage on arrival, note it on the delivery docket or reject the shipment.
