[6] Bombo station opened as the temporary South Coast Line terminus in late 1887 under the name North Kiama.

The town of Kiama, situated among fingers of hard basaltic rock running down from Saddleback Mountain to the sea, presented something of a barrier to the railway's progress further south.

[6] Over the course of the next six years after its opening, engineers and workers from the firm of W. Monie & J. Angus worked to excavate the five tunnels required to bring the line through Kiama and onto the coastal plain beyond.

[7] Though it no longer served the town proper, the station and yard remained important to the NSW Government Railways' basalt quarry at nearby Bombo Point, where mining had started in 1880.

Next to the original station building the present pre-cast concrete signal box was built in 1925 to help in handling the extra quarry, goods and passenger traffic.

[6] The line from Dapto to Kiama was electrified on 17 November 2001, allowing electric multiple unit trains to run between Sydney and Bombo; the signal box was decommissioned around the same time.

[9] Being sandwiched between Bombo Beach on one side and the six-lane Princes Highway on the other, and with only the quarries and a cemetery opposite, the station has a limited walking catchment and very low patronage (3,374 passenger movements in 2014).

Critics have suggested that trains no longer stop at Bombo, arguing for a new station to the north in the centre of Kiama Downs.

There is a layback off the eastern side of the Princes Highway south of the station to allow vehicles to drop off passengers.

The waiting room has modern floor tiling, fibre-cement sheet wall linings and gyprock ceiling with neon strip lighting, and three timber seats.
