There's no need to register a trust deed in Queensland.
When you say you've "completed a deceased estate trust deed", I'm not sure exactly what you mean by that. If someone has deceased, and you're enacting a testamentary trust, the estate should be administered in accordance with the will (including possibly getting probate, where necessary) and the relevant funds for the trust deposited into an account opened by the trustees in the name of the trust. The bank will want to see a copy of the trust instrument as part of their 'Know Your Customer' requirements under the anti-money laundering and counter-terrorism funding legislation requirements.
Also be aware that superannuation may not form part of the estate's assets unless the superannuation trustee agrees to release it to the estate. If a different beneficiary is nominated, or if there is a binding death benefit notice in place, the trustee will tax (where applicable) and then pay the proceeds in accordance with those instructions.
