SSI Takeover, the details that weren’t made public ALERT !

.
I have done some basic research trying to convince myself that buying NET was a good decision.
So I decided to look at NET's acquisition of SSI Pacific for $10.2 million.
The latest address for SSI Pacific was a tiny office of 56 sq metres at Unit 708 / 530 Little Collins Street Melbourne.
According to records lodged by SSI Pacific they have only been working there since 08/07/2019. You can not fit more that three or four people in that space excluding a reception area.
However, it is EXTREMELY WORRYING that prior to that SSI Pacific had as its principal place of business a residential property at 25b Thackeray Street Melbourne. If you search Google Maps you will realise it is a residential property in suburban Melbourne. It looks like a villa in a complex of four properties. SSI Pacific has been there allegedly doing business between 18/2/2016 to 7/7/2019. This is immediately prior to moving into the tiny office on Little Collins Street.
NO company worth $10.2 million at end of 2019 can possibly be worth that if it is working out of a residential property in suburban Melbourne. SSI Pacific's internet site consistent with this shows that the company has been dormant for several years. There is something extremely wrong about this. NET needs to make it clear how SSI Pacific was valued at $10.2 million, what was their revenue, who received the $10 million paid and how was this money distributed. What on earth is going on? I hope NET has not taken over a shell company.
