I think in most states there is a provision for EC members or their agents having access for an emergency (e.g.. there is water pouring from your unit), but that reasonable notice must be given if it is not an emergency.
The default rule in the ACT states:
What may an executive committee representative do?
- (1) An executive committee representative may do any of the following in relation to a unit at all reasonable times:
- (a) if the committee has reasonable grounds for suspecting that there is a breach of the Act or these rules in relation to a unit—inspect the unit to investigate the breach;
- (b) carry out any maintenance required under the Act or these rules;
- (c) do anything else the owners corporation is required to do under the Act or these rules.
- (2) An executive committee representative may enter a unit and remain in the unit for as long as is necessary to do something mentioned in subrule (1).
- (3) An executive committee representative is not authorised to do anything in relation to a unit mentioned in subrule (1) unless—
- (a) the executive committee or the representative has given the owner, occupier or user of the unit reasonable notice of his or her intention to do the thing; or
- (b) in an emergency, it is essential that it be done without notice.
- (4) The executive committee may give a written authority to a person to represent the corporation under this rule.
