The dam is full, the building site is levelled, the first Rabbitry
shed is on the way. The shed will be 32m X 56m. Automated manure and
urine removal/retrieval/storage is considered in two ways. Either a
conveyor belt or a horizontal auger, or a combination of both.

Picture a retrieval system beneath rabbit cages either suspended or
supported from ground level. 3 rows of cages will be installed per 8m
span of shed space, with a 1m walkway between each double bank of
cages. So 12 rows of cages will require 12 retrieval systems.

What is the best system viable and available in Australia to manage
hygiene and delivery to a collection point meeting environmental
standards?

The shed is purpose built for proper care in regard to intensive
animal husbandry. It is a "dry" shed, as in an earthen floor.
Temperature sensors will engage automated extraction fans and
raising/lowering of ventilated shed sides.

The conveyor/auger must manage at least 27m length of continuous or
regular timed circulation. That is, at least half the length of the
shed, with a break in between if need be. That means 2 belts running
in opposite directions from the centre of the shed. Better still, if
one belt can manage the entire length of 56m minus the internal
collection/cleaning point OR 56m plus a housed collection/cleaning
point external to the shed. Ditto for any suggested auger system. A
single auger/belt is OK, as central point access can be overcome by
way of a bridge.

Please refer to "Rabbit Cages and Sheds" question of 13 August, for
history on this topic. My initial question was answered with
excellence by NancyLynn.
