Australia, one of the largest non-Nato contributors to Ukraine, has been supplying aid, ammunition and defence equipment since Moscow invaded its neighbour in February 2022.

Ukraine has taken possession of most of the 49 tanks given by Australia, and the rest will be delivered in coming months, said defence minister Richard Marles.

“The M1A1 Abrams tanks will make a significant contribution to Ukraine’s ongoing fight against Russia’s illegal and immoral invasion,” Marles said in a statement.

The tanks formed part of the A$1.5 billion (US$980 million) that Canberra has provided Ukraine in the conflict, the government said.

Australia has also banned exports of alumina and aluminium ores, including bauxite, to Russia and has sanctioned about 1,000 Russian individuals and entities.

Australia’s centre-left Labour government this year labelled Russia as the aggressor in the conflict and called for the war to be resolved on Kyiv’s terms.
