Wollongong is represented here by a single office building on Burelli Street, yet its 10 units carry a median size of 190 m² and reach 520 m² — unusually large lots for a one-address market. A Wollongong tenant chasing a floor near that 190 m² median for a team of 25 to 30 has a genuine option; a two-person firm will find the 5 m² lower end of the range thinly covered.
Burelli Street runs through the Wollongong civic core, a short walk from the railway station and the council offices, which puts all 10 units next to the courts, government agencies and the professional-services firms that serve the Illawarra. For a practice with regional clients, that central Wollongong position weighs more than the choice of floor inside the building.
With 1 building and 10 units, Wollongong offers no cross-landlord comparison, so the leverage sits in timing and lease term rather than in playing sites against each other. Establish what the 190 m² median unit includes — parking bays, after-hours access, make-good obligations — because in a Wollongong market of this size those clauses, not the floor area, decide the real annual cost.
