[1] The island is named after its three most prominent hills, North, Middle and South Hummock, the latter being the highest, with an elevation of 237 metres (778 ft) above mean sea level.

[2] Much of the island is composed of dense scrub, dominated by Leptospermum scoparium, Melaleuca ericifolia and Banksia marginata, while 25% of the area is covered by Eucalyptus nitida woodland.

His son, Cecil Vernon Warne, arrived from Melbourne in February 1926, aboard the Hillsmeads, bringing the first 500 sheep to the Island.

[citation needed] Two years previously, Cecil Warne had married Dulcie Ruby Trevena in Birchip, Victoria.

[citation needed] The family lived in a house built in 1910 and Dulcie baked bread in the big wood oven, made butter and sold some at times.

Tracks were cleared around the island, with only transport being horses pulling a sled for new fence posts, tools and, sometimes, family for a weekend picnic.

[citation needed] Bill and Amelia ("Ma") Nichols leased Three Hummock Island from 1933 till 1950, grazing cattle and sheep.

Her story is told in A Walk Along the Shore[5] in which she describes life on the island with the Nichols family during the six years she lived with them, from 1937 to 1943.

Mrs Nichols named "Peg's Paddock" after her, mentioned in both A Walk Along the Shore and Eleanor Alliston's Escape to An Island.

The two books tell the story of how the Alliston family emigrated from England after the end of World War II to start a new life alone on the island, in the hope of providing a better and different childhood for their children.
