Casio FX-1AU Graphing Calculator (fx-CG50AU Successor)
The Casio FX-1AU is a colour-display graphing calculator built for senior secondary and tertiary maths, and it's the direct successor to the Casio fx-CG50AU. It's approved for use in QCAA (Queensland), SACE (South Australia/Northern Territory), and International Baccalaureate (IB) Diploma Programme exams.
Compatibility & Exam Approval
Before buying a graphing calculator for school, it pays to check it's actually approved for your exam board — the FX-1AU is confirmed for:
- QCAA (Queensland)
- SACE (South Australia and Northern Territory)
- IB Diploma Programme (DP)
If you're in Victoria (VCE) or NSW (HSC), check with your school or curriculum authority before buying — those states have their own approved calculator lists, and this hasn't been confirmed against them. It's also worth noting the FX-1AU is a standard graphing calculator, not a CAS (Computer Algebra System) calculator — if your course specifically requires CAS, you'd want Casio's ClassPad range instead.

Why This Is the Right Pick
The FX-1AU replaces the fx-CG50AU with a redesigned menu system — fewer hidden layers, a CATALOG key for every command, and a TOOLS key that adapts to whatever app you're in. It comes backed by a 2-year Casio warranty with ongoing software updates, so it's built to last through several years of study rather than one exam cycle.
