Sub-letting a room can change who lives in a home and how it is used. That can matter to a lease, strata rules and insurance disclosure. The safest approach is to establish permissions first, then update relevant information accurately.

Household arrangements can change the information on a policy.

Check the legal and lease position

Requirements differ between states, territories, lease agreements and strata schemes. Obtain consent where it is required and document the arrangement. A verbal understanding may not address insurance or occupancy questions clearly.

Tell the insurer material facts

Insurers may ask who occupies the property, whether it is owner-occupied, rented, vacant or used for short stays. Answer the actual question precisely. A change in occupants can affect eligibility, limits or conditions.

Keep boundaries clear

Agree in writing about rent, common areas, keys and responsibility for belongings. A housemate's possessions are not necessarily part of your contents sum insured. Encourage each occupant to consider their own needs.
