A4.15 – Providing for an exclusion area – S3.2 (Ratites)
Under proposed standard S3.2 the operator must ensure that a walk-through enclosure housing ratites provides at least one visitor exclusion area where animals are able to withdraw from visitor contact. For 5% of non-compliant walk through enclosures for ratites (excluding QLD which have this requirement under the base case), this would involve adding a fence or other barrier within the existing walk through area. This could be done at a cost of $500 per enclosure. Given that a walkthrough enclosure will typically house ratites along with other mammals such as macropods, this cost has already been included in part A4.2 of Appendix 4175.
A4.16 – Incremental cost of providing for appropriate enclosure height – S3.3 (Ratites)
Under proposed standard S3.3, the operator would be required to ensure that enclosure barriers for adult ratites provide containment to at least the following height:
i. ostriches and cassowaries – 1800 mm;
ii. emus – 1500 mm;
iii. rheas – 1200 mm.
The ECF agreed that a 12.5% non-compliance rate was appropriate and that an incremental cost would apply to all jurisdictions except QLD. Incremental fencing costs are assumed to include the cost of raising fence heights and taken to be $13.20176 a metre. Furthermore, given that spatial requirements are 200 square metres for a single specimen and 100 to 150 square metres for an additional adult (an average of 125 square metres) and assuming 10 animals per enclosure the average square metres per enclosure is equivalent 1,325:
200sqm + (125sqm x 9) = 1325sqm per enclosure
This would mean an average perimeter of 145.6 metres, which is calculated by taking the square root of the area and multiplying by 4. The cost per enclosure is therefore estimated to be $13.20/metre x 120.19 metres = $1,921.95.
The estimated one-off cost of providing changes to ratite fencing under proposed standard S3.3 would be $0.09m, as shown in Table A4.27.

As shown in Table A4.28, the estimated one-off cost changes to ratite fencing over 10 years would be $0.08m in present value 2012-13 dollars with 48.62% of the cost incurred by small size facilities - particularly in NSW, VIC and WA and 44.65% of the cost incurred by medium size facilities – particularly in NSW, VIC and WA.
