How to order

  1. Count your panels. One insert per bay between posts. Standard bays are 2.4 m – choose the 2.36 m panel; wider bays take the 3.1 m panel, which can be cut down.
  2. Pick your colour. All Colorbond colours are the same price.
  3. Add to cart and check out. Pay by card or PayPal. Choose courier delivery (quoted live for your suburb) or free pick-up in Sydney's west.

Delivery, pick-up and lead time

We aim to deliver within 14 days of full payment. Limited stock of 300 mm inserts can be delivered or collected sooner.

Courier delivery Australia-wide: at checkout we fetch live quotes from our freight partners (via Shippit) for your suburb and show each service with its price and estimated transit time. Long panels travel as oversize freight, so prices vary by region.

Free pick-up: Collect from our Blacktown-area depot once your order is ready. We email you when it is ready to collect – usually within 14 days of payment, sooner for stocked 300 mm inserts.

Returns

As materials are made to order, we do not offer refunds or exchanges for incorrect choice. Please make sure the post profile, length, height and colours match your existing fence before paying – if you are unsure, choose 'Match it for me' or email a photo of a post top to [email protected] first.

How to install a Colorbond fence extension – and what comes in the DIY kit

Questions about this product

Can I buy this online?
Yes. Choose your options above, add it to the cart and pay securely by card (Stripe) or PayPal. Prices include GST; delivery is quoted live at checkout or you can pick up free from our depot in Sydney's west.
How do I know which post profile I have?
Look at the top of one of your existing Colorbond posts and compare it with the three diagrams: Lysaght (A), Slimline (B) or Standard double-ribbed (C). If you are not sure, choose 'Match it for me' and email a close-up photo of a post top to [email protected] after ordering – we match it at no extra cost.
Will it fit my fence?
Extension kits suit standard Colorbond fences with sound posts and footings. The extension post slides over your existing post, so the profile must match. Standard bays are 2.4 m (choose 2.36 m); wider bays use the 3.1 m panel, which can be cut down.
How long does delivery take?
We aim to deliver within 14 days of full payment. Limited stock of 300 mm inserts can be delivered or collected sooner. Courier options, prices and estimated transit times are shown at checkout based on your suburb.
Can you install it for me?
Yes – across Sydney. Use the 'Supply + install quote' button and we will reply with a price for supply and installation based on the number of panels.
What is your returns policy?
As materials are made to order, we do not offer refunds or exchanges for incorrect choice. Please make sure the post profile, length, height and colours match your existing fence before paying – if you are unsure, choose 'Match it for me' or email a photo of a post top to [email protected] first.
