are you pretty confident that i will get a family RP
in a worst case scenario that i do not get a family RP what kind of visa will my wife get and what will happen to medical benefits etc

thanks everyone for your valuable comments and input,
further question is there any advantage in making it a fixed term contract? say 2 years?
i can appreciate that the co may be offering me a low salary since they dont have a baseline indicator of my performance. but in 2 years after i have proven my performance and we still dont agree on my value, the contract is not renewed and it automatically expires then i can seek a job in come other company?
is my assumption correct or do i still face a 2 year ban?
also i still have 1 month to join at what point of time does the company get the sponsorship rights to my WP? is it after the finger printing and govt registrations or as soon as they start processing my work visa. as in can i continue to search for a right value opportunity in the time being?
