HOBART 1805 

 …”For nearly three years - from April 1805 to December 1807 - the Derwent settlement and, for nearly that period, Port Dalrymple were very short of provisions. For most of the time both settlements were on a very much reduced ration and at some periods they were on the verge of famine. Supplies of meat were considerably augmented by the issue $53 658 per m3 $175.59 each $107.20 to $171.52 per litre of kangaroo and emu: indeed the kangaroo was the salvation of the settlements.”  https://eprints.utas.edu.au/13841/1/1988-semmens-food.pdf

…”By the winter of 1805 the convicts were down to a ration of 2 pounds 10 ounces of salt pork and 4 pounds of bread a week, a ration that in normal times would scarcely last two days. By 1806 the colony was starving to death.” - Robert Hughes in The Fatal Shore p. 125. 

…”The Hobart colony initially struggled to survive. Expected supply ships did not arrive in the first year, the small area of wheat combined with droughts in the years 1805 and 1806 instigated rations for all. Settlers turned to fishing, gathering seaweed, and prudent use of livestock. Convicts were sent out to hunt which later led to bushranging. Lack of tools hampered building and farming.” via Australian Decorative And Fine Arts Societies (ADFAS)   https://www.adfas.org.au/wp-content/uploads/2016/07/Hobart.pdf

…”The first land grants for Van Diemen’s Land were signed by Governor King on 15 August 1804. Four grants, each of 100 acres were made…  In 1805 thirteen grants were issued: these again were 100-acre allotments, except for two smaller grants of 40 and 50 acres respectively to Mary Peters and Martha Hayes. The farms extended along the Derwent River.” - Sharon Morgan, Land Settlement in Early Tasmania: Creating an Antipodean England (Cambridge University Press, Cambridge, 1992), 10.

Mary Peters was granted 40 acres of land on 18 Dec 1805 . The “Brook” that is referred to in the grant is New Town Rivulet.
