Short answer - The folks at woolies aren't here posting about it. The protesters aren't here posting about it.
Long answer - Yes, everyone has their phone when they exercise. The particular issue at hand is that exercise isn't usually done in private carparks. And it's unusual at best to be driving across the harbour to do so.
While the latest story is 'going with dad for his work related purposes' the original story given was "I was 'exercising' " (yes, the word exercising was in quotes). The implication was quite clearly that it was used as an excuse to visit to take photos rather than being in any way a legitimate reason for being there - and less than a day after responding to comments on social channels about the fact that the rules meant he couldn't visit to take photos. And it is why I used quotes around the word exercise in my post above.
Whether or not Dept Health confirmed no breach of rules, it wasn't in the spirit of them. The NSW Premier has herself called on NSW residents not to look for loopholes and to behave in the spirit of the restrictions rather than find ways around them. Sydney is in its current predicament because:
The NSW government was hesitant to bring in draconian lockdowns over a small outbreak and relied on the people to voluntarily observe the guidelines they put in place
The people took advantage of the lenient and low-detailed guidelines by finding every possible way to do what they wanted remaining within the letter of the guidelines, but clearly outside the spirit of them. (Which, being honest, is human nature).
This is why more than a month on, Sydney is plunged into a lockdown that has no current firm end-date in sight, reporting 100 new cases in the past 24 hours and 1212 active cases, and meanwhile South Australia reported 3 new cases in the past 24 hours and has a total of 14 active cases has put everyone into a lockdown that is more restricted than the current NSW restriction levels.
