Built tough, and durable enough to last a lifetime, BOAB water tanks are BPA free for safe storage of water.

Hi Kevin. Thank you for your great review and feedback. Please feel free to contact us should you require anything else.

Why Shop at 4x4 Down Under?

We know that you have a lot of options out there, and we’re incredibly grateful that you’re considering spending your hard earned money with us. We like to think we stand out from the crowd in a few ways.

Excellent & Honest Service

We try and provide the best pre and after sales service possible. If you have a question we’re here to help, and if we don’t know the answer we’ll tell you and then do our absolute best to find the answer for you. We’re also here to guide you to the best possible outcome for you. A lot of stores will simply try to up-sell you on the most expensive option. That’s not how we operate. We want to build a relationship with our customers, and the only way to do that is by being honest and direct.

4x4 Down Under is built on honesty and integrity. For example when you make a purchase with us we only charge your account once we confirm the product is ready for dispatch. Although we like to guarantee everything on our store is available we’re not perfect and mistakes do happen. If something turns out to not be available we’ll let you know immediately and you have the option to cancel your order or wait for more stock to arrive. Should you not want to wait the order is voided, and there’s no waiting a week to get your money back (it’s instant!).

Aussie and Proud!

We're Australians, and we like to support our fellow Australians, which is why all our products are sourced locally from the official Australian distributors. Nothing is imported directly and we don't stock any grey imports. This also means that all manufacturer warranties are fully honored by the brands themselves.

No Sales Gimmicks 

When you shop at 4x4 Down Under you don’t have to worry about:
  • Annoying and dishonest ’Sales Timers’ that simply reset every few hours and are there to coerce you into buying.
  • Dishonest “low stock” labels, another coercive sales gimmick.
  • False “John just bought a…” alerts. Our customer alerts (bottom left) are 100% true and we're proud of them.
  • Being bombarded by trust badges and labels everywhere you look that mean nothing. 
  • We don't spam! Your information is safe with us. It will never be shared or sold, or used to fill your inbox with garbage.

Fast Shipping with Insurance!

We've partnered with some of Australia's best couriers and freight agents to ensure your purchase reaches you in super-quick time. Once your order has been dispatched you'll receive tracking information which will allow you to track your order online every step of the way. And if something should happen to your order while in transit you can rest assured that it's insured and you won't lose a dime!

If you still have any doubts feel free to give us a call on 1300 76 86 41, or contact us here. We'd love to hear from you.

Shipping Cost

A shipping calculator can be located in your Shopping Cart. Please add your item to the cart, once in your Cart page, click "Calculate Shipping" link, enter your postcode and you will be informed of the shipping cost (if any).

Order Dispatch

Orders are usually dispatched within 1-2 business days. Should there be any delays we will let you know immediately.

In order to get your purchase to you as promptly and safely as possible we utilise a number of trusted and reputable courier services, including Australia Post (depending on the item and your location). These delivery services should have your item delivered to your door within 2 - 10 working days depending on your location. In some cases where the address is based in the more regional parts of Australia this may take longer. Should the delivery time take longer than we would like we will let you know.

As soon as the item has been shipped we will provide you with a tracking number via email. You can then use this number to watch your item make it's way toward your location. It should also give you a clear idea of exactly when to expect your item.

Depending on the item we may contact you to arrange delivery. In order to ensure your purchase lands in the correct hands we will require a signature from you on delivery. If you are not home on delivery the postman/courier will leave a card with collection details.

Please feel free to contact us should you want to make alternate arrangements for delivery. We’re flexible and here to help.

Please note that unfortunately for almost all items we're unable to ship to PO Boxes (and/or Parcel Lockers or Parcel Collect). Please rather use a street or work address, or that of a friend, colleague or family member.

We are happy to ship overseas too (depending on the item and country). Please contact us with the item you wish to purchase and your details and we’ll provide a quote where possible.
