Watch as a commuter calls out couple having sex on a bus

An Australian commuter has recorded the explosive moment he accused a couple of having sex on a public bus.

The strange encounter was captured on the 902 Chelsea to Airport West route in Melbourne which traverses past dozens of the city’s suburbs.

In the clip, most passengers are seen choosing to not acknowledge the pair’s apparent actions, before they’re called out by the man filming.

“Listen brother, you don’t f—k on the bus, mate,” he shouted.

However, the couple seemed quick to defend themselves and hollered back that they were homeless and were left with little choice about where to be intimate.

“I don’t care if you are f——g homeless, don’t f—k on the bus c—t,” the videographer said.

“I don’t care if you got autism, it doesn’t mean f—k on the bus.”

This was followed by a word of advice about where the couple should take such activities.

“Get the f—k off an go f—k in the park or something,” he advised.

The punishment for willful or obscene exposure in Victoria can be up to two years’ jail.
