Clarification on rule regarding Bluetooth

Red p plater atm have to drive down to Brisbane from cairns . Obviously not gonna drive in silence and without a GPS. Car has Bluetooth so I’ll be able to listen to music while I drive.

Wanted to check what’s the exact law regarding that, as in what do I tell the coppers if I get pulled over.

Is it just turn off Bluetooth on my phone and that’s it? And then it’s their problem to prove I’m lying? Or a better solution?
