Australian businesses have been urged to submit their applications for inclusion in the 2022 Australian Defence Sales Catalogue.

The catalogue showcases products and services from the Australian Defence industry, as well as Australian Defence Force surplus equipment available for sale under government-to-government arrangements.

Assistant Secretary Defence Industry Stephen Moore said the closing date for submissions was 23:59 AEDT on Sunday.

"Now in its sixth year, the 2022 edition will provide further opportunities to highlight products, technology, platforms and services available for export from Australia's world-class defence industry sector," Mr Moore said.

"The 2021 edition featured surplus ADF equipment available for sale to foreign government customers across the maritime, land and aerospace domains. It also showcased 214 Australian small businesses with world-leading products and services.

"It's a powerful reference for Australian defence businesses to demonstrate their innovative products and services to prospective customers around the globe."
