"""
Test that Australia region uses 'au.' prefix instead of incorrect 'apac.' prefix.
AWS Bedrock cross-region inference uses specific regional prefixes:
- 'us.' for United States
- 'eu.' for Europe
- 'au.' for Australia (ap-southeast-2)
- 'apac.' for Asia-Pacific (Singapore, ap-southeast-1)
This test ensures the Claude Opus 4.6 model correctly uses 'au.' for Australia,
and that 'apac.' is NOT incorrectly used for Australia region.
Related: The 'apac.' prefix is valid for Asia-Pacific (Singapore) region models,
but should not be used for Australia which has its own 'au.' prefix.
