Iron Knob is the birthplace of the Australian steel industry.
Iron ore was first discovered here in the mid 18th century, but it was not until 1899 when BHP (BHP Billiton/BHP Steel) was granted iron ore leases that the true value of the rich high grade ore deposits were recognised. The mine operated for 99 years with 150 million tons being mined from the twin leases of Iron Knob and Iron Monarch.
Today Onesteel Whyalla Steelworks primarily operates from Iron Duke in the Middle Back Ranges.
Situated just off Highway One, Iron Knob is 50 kilometres north west of Whyalla. In Whyalla, you’ll find plenty of opportunities for fishing, beach activities, diving and more. There’s also a Maritime Museum and plenty of places to eat and stay.
