More than 650 third-year students applied for the roles offered by the national defence and security business throughout five states.
BAE Systems chief executive Gabby Costigan said the company is excited for the opportunities provided to the students.
"I am really pleased that we can offer meaningful experiences to students over the next 12 weeks," Costigan said.
"It's important that industry provide opportunities such as these so that students can determine a career path that is going to work for them – providing them with a taste of what could be a very exciting, lifelong career within the defence industry."
The internship program is a part of BAE's two-year national graduate system, which gives participants four placements where they work on defence projects throughout the country.
Forty-three graduates were employed in 2017. Seventy-eight will join the company in 2019.
“It’s a key part of our strategy to advance the next generation of employees within our business. We are committed to investing in programs such as this to ensure that we develop the capability we need to deliver our future defence programs including the Hunter Class Frigates, the Jindalee Operational Radar Network and to support the men and women in the Australian Defence Force,” Costigan said.
