tl:dr at the end! SORRY THAT THIS WAS SO LONG
I'm making my subject selections, too! Our school also requires us to do another maths with Methods. I suggest finding whoever your school's subject coordinator is and asking them if they'd make an exception for you. Say that you'd like to do Chemistry because it's a prereq for a lot of subjects. I'm only doing Methods next year! As long as your overall grade is good enough, they'll let you do whatever you want.
(side note: GMS is
apparently easier than GMA, so if you're just doing GMA for the sake of having a maths subject, maybe you should consider GMS)
I've considered doing all the subjects that you're thinking of doing (except bio), and from all the forum posts that I've read, BusMan is a pretty dry subject (someone contradict me??). If you wanted to do something business related, I think Economics is a better choice. My parents still say that they use Economics everyday. Although, at the end of the day, what do I know? I'm only a year 10 student who's read too many ATARnotes forums and talked to too many year 11s and 12s as a form of procrastination hahahhaha. It all depends on you!
It's also a good idea to look at the teachers for these subjects, because teachers make a huuUUUUUUge difference. Talk to year 11s and 12s!
READ THE STUDY DESIGNS. Especially for Psych 3/4! It's very neurology based. 1/2 Psych focuses more on the social aspect, while 3/4 focuses on the actual brain (and behaviours too, but the brain and neurons and sciencey stuff plays a huge part! I mean, it
is a science subject). A lot of people think it's an 'easy' science subject, but beware! My friend in Year 12 says that it requires A LOT OF EFFORT. Revise, revise, revise, revise, every night for 1-2 hours. It's all about learning and APPLYING the knowledge.

Any tips for new comers to Psychology 3/4? If you're willing to do this, go ahead. I, myself, am doubting 3/4 Psych for 3/4 HHD, since I'm good at science, but it doesn't really interest me (although consumer behaviour and sociology is a huge interest of mine!)
On that note, 3/4 HHD seems very interesting! A lot of focus on the health of Australians and poverty in third world countries, etc. It seems relatively simple if you have a good English base and an interest in social change and injustices (I mean, who doesn't have an interest in this?). You should consider it because you're thinking about Bio (lol this is a stretch, I believe 1/2 HHD overlaps with Bio, but I don't think 3/4 does).
Also, if you don't know what you want to do, I think Chem maaaaay be a better choice than Bio (if they don't let you do Methods on its own) because there are more courses that require Chemistry than Bio. More often than not, doing Chemistry covers all science courses! I've asked my friends in year 11 and 12, and judging by their information, Bio 1/2 and 3/4 are both very difficult (a LOOOOT of reading), while Chem 1/2 is difficult and Chem 3/4 is fairly straightforward (provided that you learned all the foundation in 1/2, applying the knowledge in 3/4 isn't that bad!). It depends on what kind of person you are.
Of course, it all comes down to what YOU'RE interested in. You probably hear this all the time, but when you're in doubt, seriously ask yourself: Irrespective of the conflicting factors, what would you pick? (someone said this in a forum and it helped me so much).
One last thing: I feel that it's important (someone contradict me??) to have a 'creative outlet' subject, if you're that type of person. I think that when you have a subject where you're required to think in a really different way to your other subjects, it helps you relax and have fun, too. Pick your passion!
Good luck and I hope you have a clear vision very soon (sorry if I just muddled everything for you)!
btw, I'm thinking of doing Global Politics, Media, Literature, Methods, Economics, and a 3/4 (Psych??? HHD?
).
tl:dr oh shit, this is long. anyway, read the study designs and skim through the past exams from the subjects that you're looking at
