Hi NewzealandGuy,
For the english language requirements you and your partner (if you add her in your application for points) must either
1) Produce an IELTS score/certificate
2) Get a proof/certificate from your last studied college that you education is completely taught in English and also make sure your SSC and Intermediate are also having the medium as English in certificates
I have submitted my documents using option 2 for me and my spouse and they have accepted it
Now regarding the Bonus points for growth area and absolute skill shortage w.r.t work experience. As JandM mentioned your qualification and the work experience which you posses should be an exact match from the LTSS List
