There is no need for any buyer to pay for such a report unless they are under contract and need an updated financial position prior to settlement.
We have a similar system in NSW. But a proper strata report is something else entirely and can be a deep dive into the minutes, agendas and decisions of the committee, as well as a look at correspondence and finances.
There is at least one thread on this site where a purchaser was not told that, even though the block had pet-friendly by-laws, they were actively considering banning pets. And, in fact they did so between the purchaser making an offer and finalising the purchase.
A proper strata report would have revealed that and save a lot of stress and distress (all of which is redundant now, of course).
