Your MAC address can be retrieved from any router you have used to access the internet this includes at your home, work or a friend's house. Other wifi-enabled devices can include, but are not limited to, digital SLR cameras, smart televisions, gaming consoles, portable music players, Hi Fi and e-book readers. The ability to provide your MAC address for ALL wifi-enabled devices post theft is just another strategy NSW Police are implementing to locate stolen property and fight crime. It is still best practice to record the serial numbers or other identifying numbers of all your devices.
What does this mean for the general public?
MAC addresses are unique to each device, and are assigned by the manufacturer. Media Access Control (MAC) addresses are required for all wifi-enabled devices to connect to a network.
