Since this is a site weighted to NSW let me correct Flame Tree. I apologise if this is different in QLD.
In NSW only a strata manager or a committee can issue a notice to comply. The strata manager can issue one without reference to the committee. Ie they can do it off their own bat. For a committee to issue a NTC , a meeting needs to be held and a resolution passed that issues the NTC.
An owner cannot issue a NTC.
When issuing a NTC in NSW, Fair Trading has the appropriate form on their website. There are comprehensive instructions with it. If one uses the form and follows the instructions, a legally valid NTC will be issued.
