Thank you for the advice everyone.
Unfortunately The Ansett simulator can no longer be used for IPC, otherwise they would have been my first choice.
The problem now is not a checker in Australia, but is hiring a simulator. Boeing is the best option however to hire their sim you must be affiliated with an Airline, which I am not.
Part 61-4p is an option but it will be costly to do overseas.
I have emailed CASA for options as well.
This is a real problem in Australia for pilots not working for an airline, I know of 6 pilots looking to do the same as me.
