Well, in first year I didn't do any first year breadth subjects. Instead I chose: Living Longer
https://handbook.unimelb.edu.au/view/2012/UNIB30005.
Pretty easy if your good with writing an essay. Work throughout the semester is basically 0 - just once a week you write a blog about what you've learned from either the lecture, tutorial or even something that you've found interesting relating to the week's topic. There's also a wiki and a final essay. But, the good thing about the essay is that they provide the options from the start of semester - so get a head start, I finished mine during semester so that when exams came I didn't stress. Even better, is that you don't need any information from lectures or tutorials to write it. So, from day 1 you can start. And yeah ... I really liked the subject.
OR
There is this second year subject; Ecological history of Humanity
https://handbook.unimelb.edu.au/view/2012/UNIB10003I basically see it as the sister subject to living longer. Exactly the same format for assessment and essay is as well provided early on.
Both are breezy subjects, I highly recommend them and there is more information in the subject reviews on these...
Side note; the blogs take zero effort to write, each is worth 2 marks - as long as you say something interesting you'll get full marks.
