One anomaly of the 1985 WA strata laws is that the Owners Corp can pass a by-law to set a special levy that is paid equally by all owners and not on the basis of unit entitlements.
It’s an invitation to the larger property owners (who have the greatest voting power) to underestimate their levies then heap the shortfall on to everybody else equally.
There is a review of strata laws in WA underway – can’t come too soon IMHO.
