Hi!
The UNSW 2017 Co-op scholarship applications open tomorrow and I'm not entirely sure if i should enter.
You should
definitely apply. Like, whether you end up wanting it down the track or not,
definitely apply. Then you have the option if it presents itself! The application is a little intensive, but do it over your next school holidays or in the post-Trial lull. Never burn a potential bridge

Firstly, is it true that you have to decide on your degree when applying? Someone told me that the scholarship kinda locks you in early and it is difficult to work around.
As Rui said, you do need to select your degree. If you get the scholarship, you get it
for that degree - This is because, essentially, a company is paying for an
electrical engineer (for example) to get through university. It's industry focused in that way. If you wanted to swap degrees, you'd have to either hope for a Coop vacancy in that degree (if it is part of Coop), or lose the scholarship.
As a note, if you choose to leave the scholarship, you have to pay back everything you've been paid since the last industry placement you completed. So, for example, if you left the program immediately after your first placement, you'd pay nothing. If I left right now, it's been about a year since my last placement, so I pay back a years worth of payments. So it is definitely not something to choose if you think you're a high chance of swapping degrees.
Secondly, Is it true that you can't do a double degree? I read on the UNSW page that in rare cases they allow double degrees for the scholarship.
True, they tend to not like it because your focus as a Coop scholar is industry experience in
your industry. Basically, if you do a double degree, you might go to the other sector - Sponsors don't like that (at least, that's how I view the scenario).
Also from my understanding you can only do some engineering degrees for the co-op scholarship, what if you are thinking of doing another type that is not offered would it be possible? Since I am thinking about doing Mechatronics or Aerospace engineering which i believe are not on the Co-op degree list.
The scholarships they offer are based on the companies sponsoring the program that year. So unless they find a company that wants to sponsor an aeronautical engineer (for example), then they can't offer a scholarship for that program. Again, this scholarship is purely based on industry interests

And lastly, I've been told that you need to maintain really high marks to keep the scholarship (obviously you need to do this for all scholarships, however i'm just wondering whether or not this scholarship in particular is high demanding)
For most degrees, it is a Credit minimum (meaning you need to score 65+ in all your subjects). If you are able to meet the 96 ATAR cut-off, getting credits in your subjects is not that difficult (like, don't get me wrong, not saying it will be easy, but if you can get a 96 ATAR, you can get a credit at university). The academic requirements are definitely nothing to be scared of. They work with you - You aren't kicked out of the program for one bad semester or anything like that

Let me know if I can answer any more questions! But yeah,
apply, and then at least the opportunity is there should you want it, and should it present itself
