However, if you could choose either option you may be interested in a further possibility, that of natural burial.
What is the difference? With traditional burial as at Newstead, graves are set in expansive lawns which are mowed and maintained. Monuments and plaques mark individual graves. In contrast, the area for natural burials will become over time an area of re-generating native bush where the individual graves will be indistinguishable and unmarked.
Those would would prefer natural burial consider it to be more environmentally friendly than either traditional burial or cremation. They consider it sufficient memorial to have contributed to a pleasant area of restored bush.
