Introduction
Much of the early built environment at Tanilba Bay, Port Stephens, is the legacy of the renowned architect, town planner and realtor, Henry Ferdinand Halloran.
During the 1920’s and 1930’s, Halloran acquired land on the Tilligerry Peninsula and began subdividing and marketing the areas for residential housing development.
His three housing subdivisions on the Peninsula were:
Tanilba House Estate; Tanilba Bay Estate; and Mallabula Estate.
Henry Halloran had a visionary approach to urban planning and was inspired by the Garden City movement that was popular at the time. Aspects of his estate designs at Tanilba Bay can be likened to those of Walter Burley Griffin and his urban design of Canberra.
While much of the designs and features of the three estates have survived to the present, some of the planned parks were later subdivided for housing.
This paper illustrates the planned subdivisions of the above three Halloran Estates.
It is also a story in photos of the many signature features that Henry Halloran designed for the estates – stonework gates, archways, a street temple, pergola, boulevards, and parks that are evident around Tanilba Bay today.
The Appendix shows photos of Tanilba House around which the Tanilba House Estate was laid out.
Henry Ferdinand Halloran
Since his death in 1953, much has been written about this prominent businessman and property developer. He played an important role in opening up many areas for settlement in New South Wales and the Australian Capital Territory.

Henry Ferdinand Halloran
In 1897, Henry Halloran had established his own company, Henry F Halloran & Co. and had begun planning and marketing properties across Sydney suburbs and several regions including the Central Coast, Lithgow, Jervis Bay, Queanbeyan, Canberra, Lake Macquarie, and Port Stephens.
In 1913, he expanded into Port Stephens, founding Realty Realizations Limited at Raymond Terrace, and subdividing and marketing land at Nelson Bay, Tanilba Bay, Shoal Bay, and North Arm Cove, and on the northern side of Port Stephens at Pindimar and North Arm Cove.
The Newcastle Morning Herald and Miners’ Advocate of 31 October 1953, page 5, published the following obituary to Henry Ferdinand Halloran:
‘Mr. Henry Ferdinand Halloran, managing director of Henry F. Halloran, conveyancing surveyors, who died in Sydney at the age of 84, had been in practice as a conveyancer since 1897. His interests were not confined to Sydney. He was also managing-director of Realty Realizations Ltd., Hamilton, and from there controlled the activities of the two organisations in the Northern district. His country home was at Ferodale, six miles out of Raymond Terrace, where he owned a farm. Usually, he spent his holidays there. He had made a close study of animal husbandry and had shown that the country in this part of the North was suitable for pasturing sheep.
Between this suburban settlement and Port Stephens, Mr. Halloran divided his time when away from the capital. Estates were acquired, subdivided and sold at Tanilba and Shoal Bay, where there has been considerable expansion. Around Tanilba, one might see the town-planner’s impression of a well-laid out town. Thirteen estates were subdivided in this area by Mr. Halloran, who, addressing a conference of Port Stephens Shire councillors 30 years ago, said he was convinced that, with or without the railway that had been spoken of to connect Morpeth with Port Stephens, there would be rapid development.
At Lake Macquarie, he had planned and subdivided 15 estates and superintended much of the operations in the Newcastle district, with the firm’s representative (Mr. D. R. Roberts). Mr. Halloran assisted the research of the historical societies, and made available valuable data collected in the course of 50 years. The Halloran family’s link with the colony was unbroken from the days of Endeavour. Mr. Halloran’s grandfather was associated with Lieut. Caswell, believed to have been the first English naval man buried in the old cemetery behind Raymond Terrace.’
Tanilba House Estate

The Tanilba House Estate was designed to complement the historic convict-built Tanilba House and nearby lime kilns, in which lime was made by convicts to construct the house.
While developing the Tilligerry Peninsula housing estates, Henry Halloran owned and resided in Tanilba House which he acquired in 1920.

It is noted that naming of the streets of the Estate had an alliterative flair, with the first letter of the name matching that of the street’s title , e.g. Avenue of the Allies, Diggers Drive, Caswell Crescent, Army Avenue, Victory View and so on.
The street names also reflect the patriotic fervour of the First World War.
Mallabula Estate
Apart from parkland, the Mallabula Estate lacked the signature design features of the Tanilba House and Tanilba Bay Estates.
Some of the parklands, provided for in this Estate plan, were subdivided in later years for the construction of houses.

Concluding Comments
Port Stephens was fortunate in having Henry Halloran as the town planner and designer of numerous housing estates throughout the Port Stephens area.

APPENDIX
Photos of Tanilba House
In 1831, Lieutenant William Caswell, R.N., received a 50-acre land grant in what is now Tanilba Bay. Convicts cleared the land and built Tanilba House from local stone.
A 4-hectare vineyard grew east of the house in the 1830s-1840s, and an olive tree planted then still stands on the grounds. Part of a convict built stone boundary wall of Tanilba House still exists.
