Commonwealth Bank (CommBank) recently experienced a major outage due to scheduled maintenance on September 20, 2025. The outage caused disruption to NetBank, phone banking, app payments, and international transfers, lasting longer than initially planned. Services resumed on the morning of September 20, 2025, by around 10:25 a.m. AEST, but some delays in scheduled payments and transactions persisted throughout the day.
Looking ahead, CommBank has planned another maintenance window from 11:30 p.m. on Saturday, September 27, 2025, to 9:30 a.m. on Sunday, September 28, 2025 (Sydney time). During this maintenance, certain services including the CommBank app, NetBank, phone banking, scheduled payments, and transfers will be limited or unavailable. Debit card usage may also be subject to lower limits and possible declines for larger amounts. The bank has warned customers to plan ahead and be prepared for temporary disruptions during this time.
In summary, CommBank services were restored after the September 20 outage, but more planned maintenance is scheduled for the night of September 27-28, 2025, with anticipated limited service during those hours.
