Australians were quick to share their guesses with some offering more ludicrous responses.

‘It’s a public Bluetooth speaker so you can share your sick Aussie rap tracks with the whole bus,’ one person wrote.

Another added: ‘Transformer. Robot in disguise.’

‘In this case it is meant to make passengers forget any grievances they have with public transport, but it hasn’t been switch on yet… at least that is what I remember.’

There were many more jokes mocking conspiracy theorists worried about 5G transmitters.

‘I’d hazard a guess that its some sort of air filter/cleaner/scrubber as a response to covid,’ one wrote.
