Second year subjects in first year?

[Grape]

Hello!
I'm a Melbourne Uni extension program student this year and I'm considering going there next year. I'm interested in doing Commerce and have been looking at the subjects I might want to do but I've found that if I want to major in Accounting I won't be able to take their Property breadth track (which starts at second year level) because my major would have too many compulsory subjects – it is specifically stated that people majoring in accounting can’t do this track (and the property subjects are all prerequisites for each other so I can't just take one of them without the rest)
However because I will have finished two of my 8 first-year subjects this year (one core and one for my major) and will have 2 'free spaces' next year, is it possible to do second year subjects in your first year?
I have searched this up on the Melb uni website and they say you can 'overload' but I read that as to mean doing more than 4 subjects in a semester, however I am looking to still do 4 subjects a semester but have one of them being a second year property subject (economics is a pre-req so I would have to start the property in second semester anyway, after I have completed economics first sem)
If this is actually possible, is it a common thing to do? Or is it only something done by super ambitious and high achieving students and you would need special permission to do it?
If I decide to apply to Melbourne I'm equally as keen to major in accounting AND study property so I really want to find a way around this. I don't want to just do less subjects next year - I want to make good use of my head start, and I want to make the best use of my breadth subjects (with this track being the only area I’m super interested in after having a browse)
Thanks in advance

Pretty sure you can't take a second year subject until your second semester of first year (there are a certain number of credit points they make you accumulate first). This is very back-of-the-mind knowledge though, so could be wrong!

Yup, can confirm. You'll need 50 points of level 1 (i.e "first year" subjects) subjects before you can proceed to level 2 subjects.
