Why can a murderer set up companies from prison?

Stuff reports:

Notorious murderer Phillip Smith​ has spent more than a year keeping his latest round of offending – fraud of more than $66,000 – out of the public eye based on his own notoriety. …

Now he has pleaded guilty to applying for a government-run Covid-19 scheme designed to help small businesses and filing false income tax returns. …

Between October 2019 and March 2020 he incorporated five companies with the shareholders and directors being friends of associates or third parties not otherwise known to him. Smith asked for a cash flow loan of $11,800, to be used for core operating costs only, and the applications were approved. 

Then 17 false GST returns were filed, claiming $48,237 and $26,643 paid into his account and the rest to friends and associates.

How is this possible?

Do they give Smith Internet access so he can register companies and claim wage subsidies?

Does he do it via proxies? If som why are they not charged?
