The Peel Island Lazaret was the only purpose-built Lazaret in Australia: the others were modifications or add-ons to existing institutions e.g. at Dunwich, it was an add-on to the Benevolent Asylum; at Little Bay in Sydney as part of an infectious disease unit; at Fantome Island it was a former Lock Hspital.
This site plan shows the relative areas of Peel’s Lazaret.
Notes to the plan’s labels:
The Female Compound was for white females (one patient per cabin).
The Male Compound was for white males (one patient per cabin)
The Coloured Compound consisted of galvanised iron huts for the coloured male patients (four patients per cabin) and wooden huts similar to the white female huts (but accommodating six patients per cabin).

Initially the male patients huts were constructed as a square wooden box like structure, but later on, a verandah was added to the design. The white femals huts were similar but with the addition of a kitchenette with a combustion stove.
