About Defend Ukraine Appeal

Defend Ukraine Appeal is the largest Australian fundraising effort for non-lethal military aid for Ukraine. It is managed by the Australian Federation of Ukrainian Organisations (AFUO).


Until July 2023, Defend Ukraine Appeal operated under the name “U-Help”. U-Help raised over $780,000 from the start of the full-scale Russian invasion for protective gear and life-saving equipment (such as surveillance equipment, off-road vehicles and thermal imaging devices) for Ukrainian defenders. For a few years prior to this, U-Help also supported first aid and educational needs in Ukraine.


U-Help was re-branded Defend Ukraine Appeal in July 2023 to be more strongly identifiable and effective in raising critical funds for Ukrainian defenders.  Defend Ukraine Appeal continues to:

  • raise funds for the provision of non-lethal military aid to the brave defenders of Ukraine 
  • be managed by the AFUO, with the assistance of the AFUO Defence sub-committee
  • allocate funds for a variety of non-lethal military aid programs.

AFUO Defence Sub-committee

The AFUO recently formed a Defence Sub-committee that assists the AFUO Board to make decisions about how to raise and provide funds for military aid to Ukraine with the aim of saving lives.


Funds are raised through the AFUO’s U-Help fund. Donations to U-Help provide vital non-lethal military aid.


The sub-committee is chaired by AFUO Co-Chair Ms Kateryna Argyrou, and consists of 8 defence & industry experts, supported by a panel of advisers.
