Is this from Australia to the Philippines?
I don't think it's hard to convert crypto to fiat in the Philippines if the receiver in the Philippines has his own Gcash account he should able to receive crypto directly to his account because it is now available as Gcrypto as another Gcash service and directly sell it there into fiat.

Only works if it's from Australia to the Philippines but if it's different country then P2P exchange is your last hope that includes wester union like on Binance.
