NZ to Australia PT licensure

Hello, I am currently working on transferring my NZ PT licensure to Australia. I did all my education in the USA. I am a bit confused about the skilled assessment section for proof of education in the English language. None of my transcripts from my schooling have documentation on them that they were conducted in the English language (even though all of it was). I also am having a hard time getting my primary school transcripts. Is there any other option they will accept? Any other tips or suggestions for this processes would be greatly appreciated.

Thank you,
Shelby
