Our contracts and spending
Last updated: 3 Feb 2026
Find out about procurement and how to see a list of our procurement contracts of $100,000 or more, including our non-procurement contracts.
We advertise open tenders and expressions of interest on AusTender.
If you are a seller interested in tendering for opportunities with us, please become a registered seller at the AusTender website.
You can register for specific areas of interest, and you will then receive notifications from AusTender.
We request quotes and proposals from sellers in various ways.
This may be:
Our Annual Procurement Plan can be found on the AusTender website.
We make payments to sellers for the purchase of goods and services using contracts and corporate credit cards.
A contract details the goods and services we wish to purchase. The contract will include a description of the goods and may also include any delivery dates and a description of the goods or services.
When we enter a contract, it will be either:
We don't issue copies of the purchase order because the contract itself is the request to supply the goods or services. Sellers will always be advised of a contract reference number, and they are required to quote the contract reference number on all invoices connected to a purchase.
As a seller, you have the right to have complaints investigated quickly and without disadvantage.
It is best to approach the procurement contact officer in the first instance if you have concerns relating to a procurement process and wish to discuss them informally. If you are not satisfied with the outcome from these discussions, you may make a formal complaint.
Please email corporate.procurement@dta.gov.au to lodge a formal complaint. Your email should have as much information as possible, so the DTA can conduct a thorough investigation.
If you would like to make a complaint under the Government Procurement (Judicial Review) Act 2018 (GPJR Act), you should read the Government Procurement (Judicial Review) Act 2018 Resource Management Guide on the Department of Finance’s website. This will give you information on your obligations as a seller when raising a complaint under the GPJR Act.
Complaints made under the GPJR Act must be made in writing immediately after becoming aware of the alleged breach of the relevant Commonwealth Procurement Rules (CPRs).
Please lodge your complaint by emailing corporate.procurement@dta.gov.au
Once we receive your written complaint we will:
If your procurement is a covered procurement under the GPJR Act, the procurement will be suspended, unless there is a public interest certificate in place.
If you are not satisfied that the complaint has been resolved, you can apply to the Federal Circuit Court of Australia or the Federal Court of Australia for injunctions or payment of compensation for breaches of the relevant CPRs relating to covered procurements under the GPJR Act.
Applications to the court must be made within 10 days of becoming aware of the breach. A longer period may be allowed by the court if it is satisfied that the failure to make the application within this timeframe was attributable to the seller’s reasonable attempt to resolve the complaint.
We recommend you seek independent legal advice before taking this step.
You can also raise a complaint through:

Pursuant to the Senate Order for non-corporate Commonwealth entity contracts relating to the period 1 January 2025 to 31 December 2025, the DTA has no non-procurement contracts to report with consideration to the value of $100,000 or more (GST inclusive).
Estimated cost of complying with this order was $500 and the method used to estimate this cost was based on the number of hours spent on compiling this information by DTA staff.
The DTA's procurement contracts can be found through the Senate Order button on the AusTender- external site website. The report is titled ‘Senate Order - Entity Reports for complying with the Senate Order on Procurement Contracts and use of Confidentiality Provisions’.
