Giant Gippsland Earthworm are found in south and west Gippsland in Victoria, mostly on private land with limited connectivity between populations. They rely on high soil moisture almost year-round to keep their burrows suitably wet. They mostly live in clay soils on rolling to steep hills that allow surface water to build up and recharge soil moisture. Giant Gippsland Earthworms also like stream banks but always above the flood level.
