Shipping policy
At Slipstream Supply Australia we keep shipping simple: free tracked delivery on every order, sent right across Australia. Here is exactly how it works, including where your parts come from and how long they take.
Where we ship from
Slipstream Supply is a New Zealand owned and operated business, operated by Built Supply Co Limited, NZBN 9429053798558. Every Australian order is picked, packed and dispatched from our base at 40 Iwa Street, Māpua 7005, New Zealand. We stock marine and outboard parts alongside small engine and powersports parts, and we ship the same catalogue to Australia that we ship at home.
Because your order travels from New Zealand to Australia, delivery takes a little longer than a domestic parcel. We think the range and pricing are worth the short wait, and every order is tracked from our door to yours.
Order processing
Orders are processed Monday to Friday, excluding New Zealand public holidays. We aim to dispatch within 1 to 2 business days of your order being placed. During sales, restocks or peak periods this can occasionally take an extra day, and we will let you know if anything is delayed.
Delivery timeframes
The time below is an estimate from the day your order is dispatched, not the day it is placed. Add our 1 to 2 business day processing window to get the full timeline, so 7 to 16 business days from order to doorstep.
| Destination | Estimated delivery after dispatch | Cost |
|---|---|---|
| Anywhere in Australia | 6 to 14 business days | Free |
These are estimates, not guarantees. Delivery can be affected by customs clearance, courier networks, weather, and peak periods such as public holidays and major sales. We will always do our part to get your order moving quickly.
Shipping cost and taxes
Shipping is free on all Australian orders. Prices shown at checkout are in Australian dollars and include any taxes we are required to collect. For standard orders you will not be asked to pay extra import duties or taxes on delivery. If anything changes on a particular order we will contact you before we ship.
Tracking your order
Once your order is dispatched we will email you a tracking number and a link. Tracking can take 24 to 48 hours to show its first scan while the parcel moves through the network, so give it a day or so before worrying if it looks quiet.
Multiple items
If your order contains several items they may occasionally be dispatched in more than one parcel and arrive on different days. You will not be charged any extra for this. If you have received part of an order and the rest has not arrived within the estimated window, get in touch and we will chase it up.
Lost, delayed or damaged parcels
If your order has not arrived within the estimated timeframe, or it turns up damaged, contact us at support@slipstreamsupplyau.com with your order number. We will track it down with the courier and make it right, whether that means a replacement or a refund. Damaged or faulty items are also covered by our returns policy and by the Australian Consumer Law.
