Australia is negotiating a security agreement with Ukraine to boost defence co-operation and codify support following Russia's invasion.
Defence experts say such a pact could help bolster collaboration between the two nations to boost Australia's capabilities.
Largely redacted briefing material prepared for Foreign Minister Penny Wong ahead of her December 2024 trip to Ukraine confirms the possibility of a security pact, but details remain classified.
Of the 28 bilateral security arrangements finalised with Ukraine as of late 2024, none were legally binding or included mutual defence or security obligations, one briefing document noted.
Ukraine's ambassador to Australia Vasyl Myroshnychenko didn't comment on any specific provisions that had been proposed due to the sensitivities of negotiations.
But he pointed to broad areas of collaboration such as intelligence sharing, drone technology and humanitarian assistance that have been covered in similar bilateral security agreements between Ukraine and other nations.
The British pact pledged increased co-operation between defence companies and the Ukrainian army, including building military repair facilities and providing cyber defence technology.
Humanitarian provisions are outlined in Japan's agreement, which pledges to provide medical treatment for wounded Ukrainian soldiers.
Japan and Ukraine also agreed to share and protect classified intelligence.
Ukraine has developed sophisticated drone capabilities after the three-and-a-half-year war that followed Russia's invasion.
"The innovation we have, no one in the world has it", Mr Myroshnychenko told AAP.
DroneShield CEO Oleg Vornik said the war showed drones had become central to modern warfare, "necessitating rapid innovation in counter-drone technologies".
The Australian company bolstered Ukraine's defences by giving soldiers the ability to detect and disable enemy drones.
A bilateral agreement between Ukraine and Australia would significantly elevate the company's ability to "operate more directly and responsively on the ground", Mr Vornik said.
He pointed to an arrangement in place between DroneShield and Ukrainian operators to ensure technology could be rapidly updated to tackle emerging threats.
Naval warfare expert Jennifer Parker said there were important lessons Australia could learn from Ukraine, but warned Canberra "can't lift and shift the capabilities they are using because our geography is fundamentally different".
Ukraine's use of naval drones was effective at hitting Russian ships and key infrastructure such as ports, but Australia would need to project power far beyond its coastline in a conflict, she said.
"Australia needs to defend the sea lines of communications, so we need to control certain parts of the ocean for certain periods of time - you can't do that with drones, you need ships," she said.
Naval drones could help protect key choke-points around Australia but the benefit of intelligence sharing and defence co-operation with Ukraine would come from lessons in cyber warfare and how to mobilise a local defence industry to build weapons at scale to avoid becoming over-reliant on imports, she said.
