Today I received the following response from Sasha Sarago at Parks Victoria:
I apologise for the delayed response. I realised I had failed to send you a courtesy email to let you know I did receive your email upon my return from leave and have been investigating the matter since. I am currently working with my team to seek a favourable solution in relation to your concerns. I endeavour to have a response to your query by next week.

This makes it rather unclear as to what the actual state of the review by Parks Victoria of their photography and filming policy is.
