The Australian Defence Department is urging war veterans and historical groups to write in and tell them why they deserve a free decommissioned Leopard Tank.
The German-built Leopards began service in 1977 but are being phased out to make way for 59 new Abrams tanks.
The 42-tonne armoured monsters are nearly 10 metres long and come with a 105mm main gun capable of firing armour-piercing shells.
The Australian Army's Leopards have never been used in action.
To be eligible for consideration organisations need to show that the tank will have historical or cultural significance.
