Hi Mate: I have been a commercial ship surveyor for 40 years, government encourage us to do courses. Looked at The Tas. course while comprehensive and a good place to start it was far short my present standing.State authorities decided to we should all use Lloyds as the basis and accordingly
had us all do a Lloyds course in Survey and another in Ship design.
These courses were of great benefit. You might enquire from the Sydney office. Biggest cost you will have to bare is the compulsory professional indemnity insurance.
What qualifications do you have?
