From www.pobilawyers.com.au: Lot owners in a strata scheme can secure exclusive use of common property areas like attics, courtyards, and car spaces by obtaining a common property rights by-law, which requires a special resolution with at least 75% approval from the owners corporation.

Properly drafted by-laws clearly define maintenance responsibilities and boundaries to avoid legal disputes, and alterations may require development approval from the local council.

Engaging with other owners early, demonstrating minimal impact, and preparing a solid proposal can enhance the chances of approval for exclusive use rights.
