The NSW Government Railways intended for the line to eventually connect with the Sydney network in the north, and Jervis Bay or even Eden in the south.

[7] Now confirmed as a permanent railhead, and with Nowra on the Shoalhaven's opposite bank expanding, Bomaderry Station's significance grew.

A large goods yard was added, along with a turntable, dairy siding (1921), weighbridge (1921), railway crew barracks (1924) and crane (1934).

"[2] Bomaderry was also noteworthy as the terminus for the last section of the NSW metropolitan rail network to use the electric staff signalling system.

In 2005, then Minister for Transport John Watkins announced that electrification would be extended to Bomaderry at an unspecified future date, but the proposal did not progress.

[7] Tree plantings south of the station car park, north of the platform building and in the residence garden.

[22][7] A single storey brick Inter war Functionalist style building, with 2 slightly projecting decorative soldier courses (above and below window height) and a complex glazed hipped terra cotta tiled roof form.

[7] An external curved corned awning carried on round painted steel posts faces the car park.

The car park (west) elevation of the main platform building has projecting soldier courses in places.

The interior consists of a series of discrete spaces arranged on a linear pattern with direct access from the platform.

The hand painted tiles to the entry lobby and the mural to the waiting room appear to have been part of a recent community art project.

The front veranda has been enclosed with horizontal weatherboards and fixed and louvred timber framed windows, with a door at the western end.

To the north of the building is a concrete deck on a steel framed base level with the floor of the goods shed.

The goods shed features two pairs of timber tongue and grooved double doors with diagonal boarding, which face west.

[7] A freestanding single storey fibro asbestos garage at the rear, to the northeast of the residence, which has a corrugated steel gabled roof.

[7] The jib crane is located just north of and adjacent to the good shed deck/platform, and is mounted on a round concrete base almost level with the height of the platform.

It is a sunken circular brick edged structure with a single rail on timber sleepers running around the inside, and a cast iron turntable machine in the centre marked "William Sellers & Co. Philadelphia No.

At the south-western end there is a loading dock and access built in 1934 for British Australian Milk Pty Ltd. A set of points is located nearby.

[7] Two other structures associated with the station precinct are located nearby but are privately owned: Located on the eastern side of the railway tracks, opposite the southern end of the platform, within a cyclone wire fenced enclosure, the weighbridge is a small single storey weatherboard building with a gabled corrugated steel roof.

Although the building is privately owned and outside the curtilage, its proximity to and relationship with Bomaderry Station makes it necessary to consider it an important part of the site's history.

[7] Located a short distance from the station (at the northern end of the platform) is a building associated with the former Nowra Dairy Co-Op siding.

Although the building is privately owned and outside the curtilage, its proximity to and relationship with Bomaderry Station makes it necessary to consider it an important part of the site's history.
