Belmont is situated on a sandy peninsula formed by the Tasman Sea on the east and Lake Macquarie.

[3] He established small scale farming of wheat and Indian Corn and employed the local Aboriginal people to help him.

Walter St would have come right past the old Belmont house whilst Alick (named for Alexander) and Ernest Sts marked the eastern boundary of the original acreage.

On the eastern side of the old house Williamson planted a vineyard, facing towards the lagoon, and to the north an orchard including banana trees.

In 1874 he erected the first church just near where George St meets the highway, and the Belmont Post Office was opened in 1877 with Thomas Williamson himself as Postmaster.

In 1873, realising that there were enough children in the local village to warrant the existence of one, he opened the first school, a single-roomed building, next to Maudeville Cottage.

The land around the lake was of such poor quality, apart from in small patches, that as early as 1828, Henry Dangar, Government Surveyor, knew that it was more suited " to the retired naval, military or civil officer, or to the merchant, inclined to quit the busy scene, one who is fond of shooting, fishing, or hunting, or boat sailing, where he can enjoy living with a most salubrious air..." Any industrial use or mining in the lake was constrained by the terrible nature of the bar on the lake's entrance at Swansea.

[5] In addition, the New Redhead Estate & Coal Company extended their trainline to Belmont, where both a station and coal-loading ramps and sidings were constructed.

Belmont Airport is now privately co-owned by Red Bull Air Race pilot Matt Hall and a skydiving company.
