What you're missing is are two big things; what information is being captured and who is able to see it. In theory, this sounds like a fabulous idea, but when it comes to information security, you need to think that, it's not a matter of if this data gets hacked/leaked/accessed but when.
Putting that aside, lets work through the issue. The Government mandates we install this app on our phone. When do we take it off our phone? Is it when COVID is all over, if so, when it that? Is that 18 months down the line if a vaccine is available. If so, the Government now has 18 months worth of data on you, which tells them every single person your interacted with. Remember, the app doesn't care how long you interacted with the person for, just that you came in contact with that person.
Now, we've seen this particular Government put in place similar laws regarding metadata capture and who can access it. We were originally told it was to protect our country from extremists. Sounds good everyone thought; now here's a list of all the agencies who thought they should have access to our metadata without a warrant;

You may say "oh thats 2015, none of them have the ability to access it now".
Under the mandatory data retention legislation passed in 2015, the number of agencies allowed to access the data was narrowed down to just 21. But the telecommunications industry organisation Communications Alliance has revealed that at least 87 other state and federal organisations – including city councils, the RSPCA and the South Australian fisheries department – have accessed the data under section 280 of the Telecommunications Act.
Data held by the Australian Communications and Media Authority shows the power was used 8,432 times in the 2018-19 financial year, but the Acma does not record for what purpose the data was sought.

Queensland has shown that idiotic cops abuse this power and one officer was taken to court because he looked up a friends ex-wifes details and told him where he could find her and this was for a DV case.
So, with all that said and done. We have a Government who is forever encroaching on our digital lives, broadening what information they capture on us and who can access it. Can we really trust these people not to abuse this information where history has shown us that they will? Can we trust them when they tell us it will be secure? When there are countless times where personal information has been leaked from Government servers.
Most importantly, can you realistically take anything Dutton and Co say with a grain of salt regarding safeguarding us. After all, they want backdoors installed on our phones but they (Politicians) still use encrypted messaging services to circumvent Australian laws regarding record keeping.
