It is an expert opinion, otherwise known as a guess. ;-)

Using your estimate of 20 servers per agency, if each server costs
$5,000, for each 50 agencies, that comes to $5M. While that is not a
lot in the overall federal budget, it is still $5M, which can't be
spent on schools or indigenous health.

Okay, so just buy 20 severs for the application across government and
save them money on the other 980 servers.

We are talking about a system for processing job applications, not
ballistic missile defence. It is not that hard (someone tried to sell
me a ballistic missile system when I was at HQ Australain Defence Force).
As you pointed out previously, federal government agencies can't make
legal contracts with each other because they are part of the same
enterprise. As they are an enterprise it would make sense for them to
share an enterprise system for job applications. Otherwise how do you
explain to someone applying for some government jobs that they need
to keep entering the same stuff over and over again because the
different bits of the government are pretending they are separate entities?

My company web site and education server is provided by a commercial
company in Sydney and the email on a server in New York run by a
Melbourne based company. I am more than happy for them to run it on a
shared system. I use shared online services provided by several other
companies (I tried out the Google package of services for small
business but was not entirely comfortable with their "we will do
everything" approach). It would be sillily for me to run my own
servers. I have some material on my laptop, but nothing I depend on.
My laptop was used for presentations at the Open 2020 Summit.
