Australia reporting cycles and business-day rules
Australian business-day cycles run against ATO BAS reporting (monthly remitters by the 21st of the following month, quarterly by the 28th of the next month), ASIC corporate filings, and RBA RITS clearing. The Reserve Bank of Australia operates a two-tier real-time gross settlement window. AUSTRAC threshold transaction reporting follows a 10-business-day window under AML/CTF Act 2006. Single Touch Payroll Phase 2 reporting runs on each pay-event basis but year-end finalisation has a July 14 hard deadline. Public-holiday treatment under Fair Work Act 2009 follows the federal set this calculator uses.
