If I'm recommending someone for a test then I want to make damn sure I'm happy with their standard, both theory & flight. Don't forget that a school is assessed by CASA, in part, on it's rate of of 1st time passes. Why would they want to recommend a complete stranger without sufficient time to see how good you are?
As for your night experience, you need to makes sure that you meet the requirements. I don't recall that IFR at night counts. Do you have the required solo circuit time? Requirements may have changed in the years since I left Oz but you really need to go through the min. experience requirements & make sure you meet each & every one.
Just curious, but why didn't you do a NVFR as part of the time building towards your CPL?
