This is probably not a good thing to do given that they use the data to report on close and casual contacts of COVID. If you check in everywhere there is a good chance that you will get a call requiring you to self-isolate for 2 weeks.

I actually just reverse engineered the Victoria app yesterday. I don't really have any reason to do this, but if anyone does want to submit a whole bunch of check-in requests, it's pretty easy. A single CURL call will do it.
