A testamentary trust will provides advantages over a simple will. It can minimize taxes through a trust structure. It protects assets from beneficiaries' creditors through bankruptcy or marriage breakdown by holding assets in trust. It can ensure equal distribution of assets, including superannuation, contrary to a simple will. It also allows imposing conditions to protect vulnerable beneficiaries. Appointing roles like appointor and protector aim to protect the primary beneficiary's interests. A testamentary trust will can thus provide greater asset protection and tax benefits than a simple will.
