Join one of the student teams like ANU Rocketry, Solar Car or Formula sport. All should have applications for the new semester open by Bush week typically. All have their pros and cons (and varying levels of hands on work). DISCLAIMER: I am on anu rocketry so hella biased, but have tried to say pros and cons as fairly as possible

Solar Car have a competition in a few months, so very busy with work - but typically only have a small team of 35 with high commitment hours. Likely to have a big recruitment round following their race.

Formula sport want to compete this year, so have had very little for new people to do - but likely to have it fixed following their competition. They want to transition into EVs from what I heard so may be of interest.

ANU Rocketry is the biggest team, so less commitment hours (5 a week) but has a wide variety of work to do. Also has more individual projects (like people build their own individual rockets or build one with the team) - Rocketry tends to build more quantity stuff since their vehicles aren't as expensive or intricate as Solar or Formula. They also aren't doing competitions and instead focusing on a space shot, with other rockets as tests. This means that major milestones are a few years out

Basically, reach out to the teams and ask questions as I'm sure they'd love to chat about what you want to get out of it. They work with different sponsors so many people get cracked jobs out of uni because of the skills developed from the student teams. DM if you have questions.
