What do you intend to achieve By looking at the detailed accounts?
Whilst you can comMent on the magnitude of the amounts spent, the reality is that the horse has bolted. All your protests will not change the amounts spent.
You may be able to uncover fraudulent payments. You may be able to uncover payments to related parties. These are actionable but you need to be prepared to fight this through the courts. Unless you have deep pockets then forget it.
If you are concerned about the amount spent by the committee and the strata manager, then at your AGM when the motion for limiting the items that the committee can approve, have the motion set say $300. Of course you’ll need enough other owners to support that in order to pass.
Additionally, get on the committee and help the committee and the strata manager to find these cheap tradies that you know.
As others have pointed out, it is surprising how expensive a building can cost to run. And unlike your own property, because you live in a community the act says Repairs and maintenance MUST be done. They can’t be deferred.
