Ann: Top 20 Holders Report, page-97

It looks like there's about 45,000 people living in that postcode, across camp hill, carina, carina heights, and carindale. You'd expect a postcode of that size to have AT MOST about 4,000 registered active businesses in it - this isn't even adjusting for the fact that more central, CBD-adjacent postcodes are much more likely to have businesses in them. So the fact that out of over 2,500,000 active businesses in Australia, two of them share the same postcode in linked businesses, in a suburb that's only likely to have max 4,000 businesses in it, the vast majority of which will have absolutely nothing to do with the stock market... yeah, those numbers stink to high heaven. It's almost certainly the same person.
