I suggest small and relatively simple.
Do it the other way, what are the negatives of each scope?
Refractor - Generally small aperture, can have chromatic aberration and good ones are expensive.
Reflector - The dobsonian is manual, do not expect to find anything in the first 2 weeks, fairly big as that is the purpose of them. You get the biggest aperture per $, so bigish. Needs some general maintenance/adjustments.
SCT/Mak - Long focal length, reads good for magnification but small field of view and without good tracking objects drift out fast. Can be quite heavy.
In ways both the Reflector and SCT/Mak are slightly specialist.
I have suggested to people the ES Firstlight 80/640 achro on their Nano mount that they have basically for the reasons of cost and they are a reasonable general purpose scope. Guessing in Aus around A$300 (?) The other aspect is possible "enhancements".
The scope can easily have a simple white light solar filter added for solar observing. Nothing fancy but easy to do. Mind you Aus is not keen on people standing in the sun a lot.
The scope will fit on the Skywatcher Az GTi so if you stay in the hobby you can add one and have a goto system.
In effect the scope is a fair introduction.
If at Uni do they have Outreach, many do. Again the scope is kind of suitable as it is small and inexpensive. Here I find people seem to like the small ones not the large ones. Sort of opposite to what is often suggested here.
Add a town in to your profile, just useful.
Add the Uni as also, good to know. Only one I know of is Swinburn but they are heavily into Astronomy, think Brisbane has Astro also. Other will have some.
Remember that you will want likely 2 extra eyepieces, immaterial of the scope.
