Yes, on both counts.
This membership includes activities that are eligible for NAATI recertification points.
In fact, it could reasonably cover the majority of your required points over a 3-year cycle - especially when you combine the course modules, PD sessions, and mentoring.
As for tax, we believe this membership would be fully tax deductible as a professional development expense. That said, it’s always best to double-check with your tax professional based on your individual circumstances.
