Howdy!
I do engineering at QUT and am enjoying it so far. When I was deciding which uni, a lotta people told me that QUT had a more practical-based experience and things were a lot more hands-on and that UQ was more theory based. I personally could've gotten into UQ btw. Hence, I went with QUT. I'm currently majoring in Computer and Software systems, but I have a few friends who do mechatronics, so if you have any questions mechatronics related, feel free to ask. Also, I got in via early offer scheme at QUT so that was also pre good.
I suggest you go to either campus and get a feel for the vibe, and whatever you vibe with, choose that one. Idk about UQ, but most people here are pretty chill and are willing to help you out whether it be academics or career pathways.
If you have any other questions about QUT engineering, feel free to shoot 🙂
Also, what I've noticed is companies look for experience over your theoretical knowledge, so this also helped in my decision over QUT or UQ.
