COVID-19 cases by location missing data

Hi everyone,

I want sn LGA breakdown of all of NSW’s covid-19 cases. I know there’s the dataset below in the link below, but there are about 580 observations with no LGA attributed to them.

For example on 2020-03-07 has just a postcode, while on 2020-03-15, there are two observations/cases with no postcode or LGAs at all.

Does anybody know why certain cases don’t have an LGA?

Cheers!
