Victoria used to do financial services & their past papers are here:
http://www.vcaa.vic.edu.au/Pages/vet/programs/finance/exams.aspx it really only covers accounting & some of the set up is so different to what we have learnt but its good practice... & some of the business services HSC papers have some relevant questions coz some of the units overlap btwn subjects....
We did get our trial back but i've lost mine! i found that i do have copies of other exams that we've done thru the year tho so lmk if you want copies of them....
Good luck!
