Be aware that generally, a Bachelor's Degree used to lead you to a management position. There are few R&D technical roles in Australia and given the current state of the world, I'm not sure if you want to plan on looking OS for R&D work.
If you are a hands-on person, my first impression is to point you at industry after getting your diploma to get some experience - this is worth far more in job security.
On the other hand, we have call center roles here being filled by engineers with Masters degrees because there is nowhere else and stupid managers and recruiters taking them, not due to skill but because they think they're getting a 'bargain', never mind that they are completely unsuited for the role.
B.Eng is full of more maths and physics at a theoretical level, less hands-on, which may not be your 'thing' - then there is the consequential HECs debt to consider.
Build your practical skillset, try and identify a long-term niche in electronics/technology, and aim there. If, after a few years, you find the degree appealing, go for it.
This is just my personal opinion and you probably should seek wide-ranging advice to make your final decision.
