Topic	Title	Count	Per cent	Examples
1	Lack of perceived need/Low Exposure Risk and Privacy	92	45	“Because I live in a rural area and don't feel it is necessary.” “Did not see the need.” “No cases seemed unnecessary and not wanting my movements tracked.” “Privacy reasons.” “Where I live is not a hot spot, there has only been two cases and surrounding regions are quite safe.” “I didn't want to or feel the need to as the media always lets the community know (whether true or not) if there has been a case.”
2	Technical issues	49	24	“Do not have mobile phone that can download app.” “Phone wont download it?” “My phone is too old and I can't afford a new phone.” “My phone is old and is unable to download apps.” “I have heard that the App doesn't actually work on iPhones yet.”
3	Tracking and misuse of data	25	13	“We do not partake of social media or any tracing apps. I have no faith in the government or businesses in deleting the contact or information when it is no longer required.” “No one has the right to track another without there consent.” “I refuse to give the government permission to track me” “Because I would prefer to keep my private movements private, from this and any future governments, organisations or individuals.” “Do not agree with my location being tracked by an app.”
4	Trust, security and credibility	37	18	“Do not trust Commonwealth or State governments to secure data or to confine data use to COVID.” “Because I could not identify a clear purpose for this app and have a distinct lack of trust about any external party accessing my personal information.” “Just havent got around to it. A few concerns about data safety …”
