The Financial Markets Authority will oversee trustee supervision, assess trustees' suitability to be licensed and will receive regular monitoring updates from trustees.
Trustees will pay a licence fee of $4320.40 plus GST, though Power will go back to the industry as to the level of an annual levy.
The Treasury has previously criticised the annual price-tag of $600,000, saying the costs would ultimately be borne by firms seeking to raise funds.
In October last year, Power asked for submissions on the proposed legislation after trustees were included in the securities law overhaul after their failure to prevent the collapse of the finance sector through the latter half of the past decade.
In a report on the collapse, Companies Registrar Neville Harris was scathing of trustees during this period, singling out Perpetual Trust and Covenant Trustee which oversaw at least 25 failed lenders.
