Lachie Grant surveyed the property in late March and has now finished his report. The part of the report relating to the proposal is copied below, along with a link to the full report.
2.3 SUMMARY OF PROPOSED CHANGES IN FARM PRODUCTION
The proposed development involves converting 5.0ha of effective pastoral land into 10 housing lots resulting in 25.9 ha remaining in effective farm land. Construction of an all-weather access bridge and establishment of amenity and shelter plantings are also projected as part of the development.
Effective productive area
|Blocks||Existing Area (Ha)||Developed Area (Ha)|
|Total property area||32.7||32.7|
|Effective productive area||30.9||25.9|
|Lots 1-10 (Lot 5 house site only)||–||5.0|
* Non Productive areas include in-effective pastoral land, waterways, forest and scrub.
The proposed subdivision will reduce the effective area to 25.9 ha. With improved pasture production through farm management techniques such as increased soil fertility, further subdivision, strategic applications of nitrogen, fodder crop production and grazing management, the property is capable of producing 7,000 kg DM/ha and running 8.6 su/ha.
The current stock policy of running breeding cattle and has an estimated gross margin of $53/su ($12,720 over 30.9 ha).
Three other farm systems were modelled for the property and included intensive bull beef finishing, heifer finishing and dairy grazing. All three modelled systems (which are capable of being undertaken on the property) significantly outperformed the current system despite the reduced effective area as a result of the subdivision. It is estimated that the gross margins from the diary grazing, heifer finishing and the bull beef finishing are $28,000, $23,100 and $38,800 respectively (with 25.9 ha). These modelled systems would, however, require more intensive management along with increased subdivision, soil fertility, and improved pasture composition. This could only be made possible with intensive management associated with permanent access (a bridge) across the Roding River and possibly living on-site.
