I'm glad you've answered first up Dave, because I'm an Australian like yourself (just down the road in Wollongong, no less).
I was planning to do an Advanced Diploma in "Electronic Technology" at TAFE (I posted the link here and you responded to that), which if I'm able to do, will be doing part-time, so that's a four year course as it stands.
Are there any electronics engineering cadetships available in Australia, to your knowledge? Is there a major advantage to having a Degree as opposed to an Advanced Diploma or similar?
Electronic cadetships? Not really that I'm aware of. Cadetships are really a trade level thing.
Having a degree gives you that wanky bit of paper that supposedly makes you a "real" engineer, and yes, there are a few companies around that are very strict on this requirement.
But in general it all comes down to your actual experience, once you get a foot-hold into an engineering level job then what course you did or where you did it becomes almost pointless.
You can even get a professional graduate level status from Engineers Australia without any qualifications, provided you can prove you have the relevant experience.
Technically there are 3 levels of professional engineering qualifications in Australia. 2 year Diploma level, 3 year "technologist" level, and 4 year "bachelor" level.
Here is a list of technologist level courses:

In practice no one really cares about the Technologist level, and it can in fact fool many people because it has the worlds "Bachelor" and "degree" in the title so can sound like a full 4 year traditional engineering degree.
If you have the time, inclination, money, and patience to sit through endless boring math, physics, and advanced theory classes whilst learning little real practical electronics, go for the full degree. Because then you automatically tick the box on job requirements that say "degree", and you sail through step #1. If not, then it's possible to get a great professional design engineering job in the industry with just a Diploma level (or even nothing at all), but you have to work harder at it.
But like I said, it all comes down to what experience you have. if you want to get into electronics engineering then it's vital that you get out of that "trade" level job and into an electronics engineering job and work your way up. just by being enrolled in a Diploma or Degree part time is usually enough for you to go looking for those level graduate jobs even though you are no where near graduating yet.
