In 1879, Australian bushranger and outlaw Ned Kelly devised a plan to create bulletproof armour and wear it during shootouts with the police. He and other members of the Kelly gang—Joe Byrne, Steve Hart, and brother Dan Kelly—had their own armour suits and helmets crafted from plough mouldboards, either donated by sympathisers or stolen from farms. The boards were heated and then beaten into shape over the course of several months, most likely in a crude bush forge and possibly with the assistance of blacksmiths. While the suits successfully repelled bullets, their heavy weight made them cumbersome to wear, and the gang debated their utility.
Also on display are Kelly’s Snider Enfield rifle and one of his boots.
I watched a documentary about him a long time ago by Mr Serious

Serious did another about the inventor of beer foam, definitely recommended.
