Purpose of "" in COVID-19 cases by location?

In the COVID-19 cases by location data-set, I notice the use of “” in various places. Are these spaces and hence unknown locations, or are they representing that these tests are the same identical location to the positive test case directly above them?

For example the following 4 rows in the data-set:

|2020-07-26|2048|X700|Sydney|14170|Inner West (A)|
|2020-07-26|2145|X740|Western Sydney|12380|Cumberland (A)|

Are rows 2 and 3 in the above to be considered identical location cases to row 1?
