Staffed lockup vs. unmanned lockers
Staffed luggage storage runs $7–$10 per bag per day in Sydney and almost always includes CCTV, on-site security, and per-bag insurance. App-based unmanned lockers are cheaper at $5–$7 but rarely insured beyond a token amount.
If your bag contains anything irreplaceable — passports, laptop, expensive camera — staffed is the only sensible option.
Hotel cloakrooms
Most Sydney hotels will hold guest bags for free on the day of arrival or departure. Non-guest bag-holding is usually not available, and where it is, there's typically no insurance.
Best fit by trip type
Day-trip with one bag: app locker is fine if you're at the airport or CBD all day.
Cruise or hotel-gap day: staffed storage with insurance is worth it.
Multi-day storage between Airbnbs: weekly rates from staffed providers (around $35/bag/week) beat hotels and lockers.
