Sounds like you'd be interested in a degree like Arts/Economics, Arts/Commerce, or PPE (As mentioned, it's at Latrobe, but it's also well established at ANU if you're willing to go interstate).
When it comes to commerce, it sounds like you'd be interested in Economics, Finance and maybe International Commerce/Business (I would view the latter as kind of a 'soft' major of limited career assistance, but it's an option). How much maths is involved in these majors kind of depends on what units you take. A lot of the finance major is actually plugging numbers into a formula rather than 'maths' so the numbers part isn't too bad in that respect. It's a narrower major than economics though, and many of the subjects aren't really linked to politics, history, or international ramifications. There are a couple of exceptions (e.g. International Finance, which is one of the better units in the major imo) but it sounds like your interests lie closer to economics. Having said that, finance might be a good second major as part of a Arts/Com degree.
I haven't done a lot of economics (only did the first year units, majored in finance), but as you can see -
https://www.monash.edu/pubs/handbooks/aos/economics/ug-bus-economics.html - there are quite a few options re: electives. From what I understand, the core units towards 2nd/3rd year can involve quite a bit of maths (like, proper calculus), although I suspect that like the finance major, you can structure your degree somewhat to avoid doing too much of this.
