        The results of the modelling indicate that the cumulative impact of the litter
        stockpiling and the proposed eight shed poultry farm can comply with the
        relevant odour amenity criterion subject to the implementation of best-practice
        farm management practices.


   •    The quantitative odour impacts of spreading spent litter across the footprint of the
        existing avocado farm.

        The site has operated as an avocado orchard for over 15 years and prior to
        that as a range of fruit orchards. Fertiliser application is an integral
        component of the existing use and advice from the proponent is the manures
        have previously been applied at the site without generating any significant
        odour nuisance. Imported manure-based fertiliser may continue to be used at
        the site but the primary driver for moving away from the use of manures was
        the relative cost of this fertiliser.
