The Dept of Health site doesn't seem to mention an exact distance, but a huge number of other sources all use the figure of 1.5 metres.
eg.andThe only information they are allowed to access is that of close contacts – when a person has come within approximately 1.5 metres of another app user for 15 minutes or more – in their jurisdiction,” Minister Robert said.
I suppose it is possible that one person like the Minister for Government Services made up the figure of 1.5 metres and every other source is just repeating that.Released on Sunday, COVIDSafe uses Bluetooth to connect with other phones within 1.5 metres (4.9 feet) which also have the app installed. If they are in contact for over 15 minutes, the app records data such as the date, time, contact distance and duration, and the other user's encrypted identification code. This information is stored on the user's phone for 21 days, after which it is automatically deleted.
However, since the official Dept of Health site mentions that distance is one of the pieces of data recorded, it seem logical that the app is not simply recording every contact that comes within the maximum range of bluetooth on that particular device.
If officials are using that figure of 1.5 metres, then even allowing for the inaccuracy of bluetooth distance measurement, it seems unlikely that contact would be recorded for a phone 10 metres away.
