Caterpillar is the most common heavy equipment brand on Australian mine sites and civil projects. For mining contractors, earthmoving crews and workshop teams running Cat fleets, ordering Caterpillar parts online has become the fastest way to keep machines turning — especially during shutdowns, scheduled servicing and breakdowns.
This guide walks through how to buy Cat parts online in Australia, which Cat dealer covers your territory, how to find the right part the first time using the Caterpillar parts catalogue, and how to tie every order back to a job and an asset.
Caterpillar parts Australia: which dealer covers you?
Caterpillar doesn't sell Cat parts directly in Australia. Instead, four authorised Cat dealers cover the country by territory. Your dealer is set by the location of your machine, not your head office.
| Cat dealer | Territory | Online ordering |
|---|---|---|
| WesTrac | WA, NSW, ACT | Parts.Cat.Com + WesTrac OneAccount |
| Hastings Deering | QLD, NT | Parts.Cat.Com + Hastings Deering portal |
| Cavpower | SA, Broken Hill | Parts.Cat.Com |
| William Adams | VIC, TAS | Parts.Cat.Com |
What is Parts.Cat.Com?
Parts.Cat.Com is Caterpillar's official online parts store. It sits in front of every authorised Cat dealer globally, including Australia, and is the single best place to buy Cat parts online with account pricing. Once you're signed in, you can:
- Search the full Caterpillar parts catalogue by serial number, part number or category
- View exploded assembly diagrams from genuine Cat parts manuals
- See live stock at your nearest Cat dealer branch and your account pricing
- Order Caterpillar parts online 24/7 with pickup, freight or hot-shot delivery
- Track orders, invoices and dispatch notifications
- Save kits and templates for repeat service intervals
Who should be ordering Cat parts online in Australia?
Any Australian business running Cat mining, earthmoving or construction equipment benefits from ordering Cat parts online — mining contractors, civil contractors, drilling and blasting crews, port and rail operators, and independent workshops servicing Cat fleets. If your team is still phoning every order through, the Caterpillar parts catalogue online will save hours every week and cut wrong-part returns.
How to buy Cat parts online: step by step
1. Confirm your Cat dealer and customer account
Caterpillar Australia is split across four authorised dealers — WesTrac, Hastings Deering, Cavpower and William Adams. Make sure your business has a customer account with the dealer that covers your machine's location, linked to your ABN and authorised buyers. Without an account you can't buy Cat parts online with account pricing.
2. Log in to Parts.Cat.Com or your dealer portal
Go to parts.cat.com or your dealer's portal (e.g. WesTrac OneAccount or Hastings Deering's customer portal) and sign in. Parts.Cat.Com is Caterpillar's global online parts store and routes your order to the correct Australian Cat dealer automatically.
3. Search the Caterpillar parts catalogue by serial number
Enter your machine's serial number (or a known part number) to load the correct genuine Cat parts catalogue for that build. The portal shows exploded diagrams, live stock at your nearest branch, supersessions, and your account pricing.
4. Add Cat service parts to your cart
Build your cart from the catalogue, double-check quantities and serial-number compatibility, and save common service-kit templates so your team can re-order the same Cat filters, hoses and wear parts every interval without rebuilding the cart.
5. Choose pickup, freight or hot-shot delivery
Select branch pickup, scheduled freight to your workshop, or hot-shot delivery for breakdown jobs at remote mine sites. Enter your internal PO number so your accounts team can match the Cat invoice straight back to the job and asset.
6. Submit, track and reconcile
Submit the order, then track confirmations, dispatch notifications and invoices through the portal. Record the Cat order number against the job and asset in your job management software so the parts cost flows into job profitability and the machine's maintenance history.
Finding the right Cat part the first time
The most common cause of wrong-part returns is searching by model rather than serial number. A Cat 793F built in 2014 has different filters, hoses and sensors to a 2022 build — even though the model is the same. When you order Caterpillar parts online, always start with the serial number so the Caterpillar parts catalogue loads the correct manual for that build and blocks you from picking a superseded part.
For older Cat machines, photograph the part and the data plate before you order. Cat dealer parts interpreters can confirm fitment from a photo and a serial number faster than from a phone description.
Delivery options: branch, freight and hot-shot
| Delivery type | Best for | Typical lead time |
|---|---|---|
| Branch pickup | Workshops close to a Cat dealer branch | Same day if in stock |
| Freight to workshop | Scheduled servicing & shutdown parts | 1–3 business days |
| Hot-shot to site | Breakdowns at remote mines | Same day where available |
| On-site stock holding | Major mining contracts | Immediate from site store |
Online vs phone orders for Cat parts
| Factor | Parts.Cat.Com (online) | Phone to dealer |
|---|---|---|
| Available hours | 24/7 | Branch hours |
| Stock visibility | Live across the dealer network | Verbal check |
| Audit trail | Order history & invoices in portal | Phone log + email |
| Best for | Planned servicing & repeat orders | Complex breakdowns needing advice |
Tying Cat parts orders back to jobs and assets
The real value of buying Cat parts online comes when every order is linked to a job and an asset. Without that, parts cost lives in your accounting system and never connects back to job profitability or equipment maintenance history.
In SprintSuite Procurement, you raise a purchase order against a job, record the Parts.Cat.Com order number, and let the Cat invoice match against that PO when it arrives. From there, the parts cost rolls into job management and the work history of the machine in asset management.
That means the next time you quote a similar job, your numbers are grounded in real Cat parts cost — not a guess.
