The Careers Day will attempt to address the skills shortage and the widening age gap threatening the industry.
Speakers and exhibitors will include representatives from Woodside, Subsea 7, Technip, OilCareers, The University of Western Australia, Wood Group Kenny, Schlumberger and Fluor among others.
Students will hear free presentations, learn about career pathways and pick up job search skills.
AOG event director Bill Hare said it also provided a significant opportunity for leading oil and gas employers.
"Securing, training and retaining emerging talent are integral to the continuing growth of Australia's resources industry," he said.
"We see the Careers Day as not just an opportunity for students, but also a chance for employers to talk directly to hundreds of top maths, science and engineering graduated and get them thinking about a career in the industry."
AOG Careers Day is on today at 10am-2pm at the Perth Convention and Exhibition Centre.
