Its 1943. Its hot. The terrain steep. The conditions are not much better. And you and your team need to build 5 oil tanks. Welcome to Darwin! These five storage tanks are located at different locations along the Darwin cliff face. 1 Located in Larrakeyah, another at Doctors Gully and 3 along the Bicentennial Park. Get up close like no one has before and view these grand tanks. One (at Doctors Gully) was even transferred into a rock climbing facility - The Rock Centre!
