An Australian Machinery and Equipment Bill of Sale is a written legal document that records the sale and transfer of ownership of industrial plant, machinery, or equipment from a Seller to a Buyer. It captures all essential details of the transaction: the identities of both parties (including their ABN or ACN), a precise description of the plant (including the serial number, model number, year of manufacture, and current location), the purchase price, the GST treatment, the condition of the plant at the time of sale, any attachments or accessories included in the sale, WHS compliance disclosures, hazardous materials disclosures, any transferable manufacturer’s warranty, and the moment at which title and risk of loss pass from the Seller to the Buyer.

Industrial plant and machinery are significant capital assets for most businesses. Unlike standard consumer goods, high-value plant and equipment is subject to a range of legal obligations that go beyond the basic sale of goods framework. Australian WHS legislation imposes obligations on designers, manufacturers, importers, suppliers, and users of plant to ensure that it is safe. Certain categories of plant are required to be registered with the WHS regulator in the relevant state or territory before they can be used.

The legal framework governing machinery sales in Australia is shaped by several key legislative instruments. The Work Health and Safety Act 2011 (Cth) and its state and territory equivalents govern plant safety, registration, and compliance obligations. The Personal Property Securities Act 2009 (Cth) (PPSA) governs security interests in machinery and equipment. The Australian Consumer Law (ACL) applies mandatory statutory guarantees to sales of goods in trade or commerce. The A New Tax System (Goods and Services Tax) Act 1999 (Cth) determines whether and how GST of 10% applies to the sale.

An Australian Machinery and Equipment Bill of Sale is needed whenever industrial plant or equipment changes hands and the parties want a written record of the transaction and the transfer of title. A Bill of Sale for machinery is important in a wide range of commercial and industrial contexts:

Surplus equipment disposals. When a business sells surplus or no longer needed machinery — such as manufacturing equipment, construction plant, agricultural machinery, or food processing equipment — a Bill of Sale records the agreed terms and (where the seller is GST-registered) supports the issue of a tax invoice.

Business asset sales. When a business sells part of its assets (but not as a going concern), a Bill of Sale for each item of plant is essential for recording the transfer of title and for accounting and depreciation purposes.

Construction and mining plant. For high-value plant such as excavators, bulldozers, cranes, and drilling rigs, a Bill of Sale is essential for PPSR registration purposes and to document WHS compliance obligations.

Auction and liquidation sales. When plant is sold by auction or by a liquidator, the Bill of Sale provides a formal record of the transaction and the seller’s authority to sell.

Deferred payment or instalment sales. Where the buyer does not pay the full price at the time of delivery, a retention of title clause combined with PPSR registration protects the seller’s ownership interest until full payment is received.

A well-drafted Australian Machinery and Equipment Bill of Sale should include the following key elements to be legally effective and protect both parties:

Detailed identification of the plant. The machinery should be described with sufficient precision to identify it uniquely. This includes the make, model, year of manufacture, serial number, model number, capacity or specifications, hours of use (for mobile plant), colour, quantity, and current location.

Purchase price and GST treatment. The price must be stated in Australian Dollars (AUD) and the GST treatment specified clearly. For commercial sales by GST-registered sellers, a tax invoice must be issued.

WHS plant compliance disclosure. The Bill of Sale should state whether the plant complies with applicable WHS legislation at the date of sale, or whether the buyer is purchasing on an as-is basis.

Hazardous materials disclosure. Where the plant contains or is associated with hazardous materials (such as asbestos insulation, hydraulic oil, refrigerants, or lead-based paint), this must be disclosed.

Manufacturer warranty transfer. If a transferable manufacturer’s warranty remains on the plant, the Bill of Sale should record the warranty details and the seller’s obligation to assist with the transfer.

Transfer of title, risk, and delivery. The Bill of Sale should specify when title and risk pass, and which party is responsible for collecting and transporting the plant.

Retention of title and PPSR registration. Where the buyer pays in instalments, a retention of title clause and PPSR registration protects the seller’s ownership interest until full payment is received.
