Commuter Chaos Expected As 115 Bus Drivers Call In Sick

If you're planning on catching a bus home from the city this afternoon, you may need to rethink.

Commuters using Hillsbus, which services the North-West area of Sydney, were urged to allow plenty of extra travel time on Wednesday after 115 bus drivers called in sick.

Transport NSW and Hillsbus apologised for the delays, which have caused overcrowding in buses and stations across the city.

The number of drivers calling in sick is six times higher than average, Hillbus said.

"Hillsbus sincerely regrets the disruption and inconvenience caused to our customers. We are working to operate as many services as possible, however, there will be some cancellations and delays this afternoon on some routes," a Hillsbus spokesperson said in a statement.

"Customers travelling from the CBD in particular should consider travelling earlier or using alternative transport options where possible."

Frustrated commuters have taken to social media to express their outrage at the situation.
