Our story

However you found us, we're glad you're here. Let us tell you our story...

De Stefano & Co is a defence-focused management and security consultancy that assists businesses from across Australia and the globe in navigating the complex Australian defence industry environment.


Our Director & Principal, Emilio De Stefano, founded De Stefano & Co in 2015. After spending the first 10 years of his career working in electronic warfare for the likes of BAE Systems prior to joining a heavy engineering SME working in support of the Collins Class Submarines, Emilio was given the opportunity to undertake some study in the US. It was there he realised that he wanted to do something more for the broader industry base, so he came back, handed in his resignation, and De Stefano & Co was born...


Soon after it was established, companies started coming to De Stefano & Co asking for help to break into the sector and win work. For many, the defence sector is a complex and highly bureaucratic beast, with those brave enough to enter its lair quickly learning that nothing happens overnight, and there are many hurdles to jump over along the way. Given Emilio's background and experience in the sector, he was well-placed to support those companies on their journey.

Fast forward to the present, and De Stefano & Co is now a team of 17 defence and security professionals, highly experienced in their respective fields. Visit the Our team page for more information about our key team members.
