The normal process would be that the miscreants would receive a Notice To Comply which may include a deadline for them to comply.
Failure to abide by the by-law would then normally result in the owners being taken to NCAT by the owners corp/strata manager/committee who would apply for a penalty to be imposed. The maximum fine is $220. You might want to keep on top of this as the committee will have to instruct the strata manager to take this to the next stage, which offers another opportunity for dithering and delay.
If the problem continues after the fine has been issued and paid, the OC can possibly move on to having the dog either removed from the building or effective measures being taken to quell the barking.
You have to go with your strata manager’s judgement on this as they are likely to be the ones prosecuting the case. So keep on good terms with them and make sure that when they apply to NCAT (if the NTC is ignored) that they apply for costs. That not only increases the financial hit on the dog owners but reassures the committee and other owners that strata funds aren’t being “wasted” on “personal disputes” between owners.
Another reason for acting swiftly and keeping up the momentum on this is that NCAT is currently understaffed, underfunded, overworked and has a backlog of cases. Justice delayed is justice denied.
And the committee really needs to get moving on getting the strata roll updated, not least because of the pandemic. And continually receiving several NTCs is just as much an indication the residents refuse to behave properly with respect for strata law and by-laws as it is a sign of alleged harassment.
