You started your post with an insult, then finished with a comment re throwing a net over me. From the latter I wondered if you had interpreted the incident as 1000ft.
Anyway lets not argue minor points. I agree the ABIT was a bit pie in the sky. The aircraft involved was a straight hang glider, not a powered trike. I was simply trying to make the point that in Class E airspace, there can be no radio no transponder traffic, particularly in NE Victoria, where they operate up to 10k. Large numbers during the Summer months in particular.
I think you mentioned earlier a guesstimate re the numbers, and said they needed to be factored into any risk assessment. I agree
