I was circumnavigating my neighbourhood when I was confronted by a female grey kangaroo and her joey on a pathway between two houses. The scary thing at the other end of the pathway forcing the kangaroos in my direction was a lady with a pram. So anyone who thinks my face scares small babies should note that, to an animal, I am less frightening than a lady with a pram.

For the Grey Kangaroos in our area the urban environment provides a welcome source of green feed. The bush in our area is Sclerophyll forest and, in summer, is dry with reasonably unpalatable grasses and bushes.

"Sclerophyll forests are a typically Australian vegetation type having plants (typically eucalypts, wattles and banksias) with hard, short and often spiky leaves, which is a condition closely associated with low soil fertility (rather than rainfall/soil moisture). Low fertility also makes soils undesirable for agriculture and native vegetation has, therefore, remained relatively intact. 

Plants grow slowly in nutrient-deficient conditions and some species have developed symbiotic relationships with nutrient-fixing bacteria and fungi to enhance nutrient availability. Others have root systems that increase the efficiency of nutrient uptake."

Eucalypts have extensive root systems which rob the soil of moisture so grasses tend to be dry and uninviting.
