Residents of almost 40 Adelaide suburbs will have their deliveries cut as Australia Post responds to changes in demand with COVID-19.
A number of southern and western suburbs will now only get deliveries of letters every second day.
The changes are being made to allow Australia Post to make more parcel deliveries following unprecedented demand in parcel post.
Australia Post says that the changes are only temporary, with affected residents being made aware of the change via a postcard in their letterbox.
It is unclear why Australia Post has only selected certain suburbs for the change.
