These are two totally different things – a trust is an arrangement between 2 or more parties. It is a set of responsibilities that are imposed on a nominated party (the trustee) to hold assets on behalf of another party. A company is a legal entity registered with ASIC, that exists separately from its owners (its shareholders). A company’s status as a separate legal entity gives it the same rights as a natural person, meaning it can be sued, is liable for debts and it can sue another entity.
