Zenit-Australia is a two-stage launch vehicle. It is a development of the Zenit-3SLB launch vehicle that operated from the Baikonur launch site as a Land Launch project, and accounts for the experience gained from the USA Antares program. Zenit-Australia has been developed by Ukrainian rocket provider Yuzhmash, under contract with the Cosmovision Global Corporation.

It uses only environmentally-friendly fuels and is capable of injecting payloads of 5500kg to Geotransitional orbit, 8500 kg to 500 km Sun Synchronous orbit, and 15500 kg to the reference 200km Low Earth Orbit. Zenit-Australia is a further development of the world's most advanced launch vehicles, including the highly successful Zenit-2, Zenit-3SL, and Zenit-3SLB, with the benefit of new experience acquired while developing and manufacturing the 1st stage of the USA Antares launch vehicle. Zenit-Australia uses new propulsion systems for both stages and is completely free of components from Russia or China, employing American or Australian sourced equivalents in their stead.
