UTR,
Brisbane was one of the first to be published and unfortunately predates the naming convention we have today.
Unfortunately, it's not easy to change under the current data change rules. We can't simply swap them round in one cycle, it would take 3 cycles. The -z would have to go to an -x, then the -y would have to swap to the -z, then the -x would go to a -y....over 3 cycles. Bit confusing and probably safer leaving it as is.
