Shipping

Free shipping Australia-wide on most orders, including tailgate delivery on larger items in most areas. Orders are usually dispatched within 1-3 business days, with delivery around 2-7 business days depending on your location, and you'll receive tracking as soon as your order ships. Every now and then, a delivery to a rural or remote area, or one that needs a tailgate in a harder-to-reach spot, falls outside standard freight and there may be an additional charge. If that applies to your order, we'll always contact you with a quote before dispatch, and you can approve it, choose free collection from your nearest depot or cancel for a full refund. You're never charged extra without your approval. See our full Shipping Policy for details.

Returns

At Prestige Power, we fully stand by every product that we sell. Still, we know that sometimes you might change your mind or you realise the product you ordered wasn't exactly what you were hoping for. That's why we have a 30 Day Return Policy, so you can shop with confidence and know that if something isn't right, we'll help make it right.
