Of course the statutory manager can set the levies – otherwise they wouldn’t be able to manage the building. You can appoint someone to view the documents on your behalf. And if you are unhappy with your strata manager, next time don’t go for a statuory appointment, just ask for NCAT orders to have them removed (but you’d better have good reason).
You might want to look at hiring a strata advocate to represent you like Nick penny (nickp@intensive-care.com.au) or the team at Strata Answers.
