De Garis' father had established a successful
market garden business in Mildura from about 1885. In 1908 the day-to-day business was left to C. J., and Elisha moved to Melbourne establish a selling agency for the business. C. J. was just 17, but had a strong self-belief and effervescent charm. Theatrical entrepreneur
Claude Kingston described him as the "prince of ballyhoo". The estate was moderately successful as a farm produce settlement, but in 1921 it was broken up and sold to fund De Garis's
Kendenup venture. £23,000 was raised from the sale. In 1919, a shortage of shipping space hit the dried fruits industry which was, at that time, highly dependent on British markets. Realising his ability to market, the Australian Dried Fruits Association funded De Garis to undertake an Australia-wide publicity campaign to increase domestic consumption. He also expanded into book publishing, as well as, with
Harry J. Stephens, producing the
Sunraysia Daily newspaper in Mildura, employing nearly 100 staff. Also in 1919, De Garis exposed a con-man, with a "rank but not-too-well-sustained American accent", named George Henry Cochrane. Cochrane wrote for
The Bulletin as "Grant Hervey", and had recently been released from prison for forgery and uttering. Cochrane emerged in Mildura and presented himself to two thousand Mildura citizens, selling the idea that western Victoria, including Mildura, should
secede from
Victoria. He started receiving £5 subscriptions before De Garis revealed his true identity and criminal record. As part of his dried-fruits marketing De Garis travelled to
Western Australia where, in 1920, he purchased the property of the Hassell family at Kendenup, for the purpose of building a new settlement to grow apples, potatoes and farm produce. He subdivided the land into blocks ranging from to , and set up the De Garis Kendenup (W.A.) Development Company, and the Kendenup Fruit Packing Company, which ran a dehydrating factory to process vegetables and fruit grown by the 350 settlers who he had encouraged into the area. In December 1921, De Garis and his family were living there, and the enterprise was under way, with a townsite being established. However the settlement eventually floundered. It had insufficient capital and the lot sizes were uneconomically small. De Garis travelled to the United States to raise urgently needed capital, which was promised but was never forthcoming. After two years, only 30 settlers remained. The collapse of the settlement was the subject of a 1923 Western Australian
Royal Commission into Kendenup land schemes, in which fraud had been alleged. De Garis was eventually cleared of any charges. ==Artistic endeavours==
