[1] In 1999, along with Town Hall, the station received an easy access upgrade which included lifts to each island platform.

The station was extensively refurbished in 2016, with Wynyard Walk, a pedestrian-only tunnel, being officially opened on 20 November 2016.

Later, the platforms were walled off from 3 and 4 and part of the space converted into an underground car park for the Menzies Hotel.

[6] The remainder of the tunnels north of the car park exit were walled off as were the northern portals on the Harbour Bridge.

North of the portals, two additional road lanes were built above the old tramway as part of the Cahill Expressway.

Parts of the former escalators were repurposed into a ceiling-mounted artwork titled 'Interloop', which was installed at the York Street entrance to the station concourse.

Wynyard Walk provides direct access via tunnels to Clarence, Kent and Sussex streets.

[16] East of the railway station on George Street is the Wynyard light rail stop, which is the serviced by the L2 Randwick and L3 Kingsford lines.
