“Wingecarribee Shire is an important catchment area for water supply to Sydney, Wollongong and the Northern Shoalhaven.”



Wingecarribee Shire is the local government area of the Southern Highlands in the state of New South Wales, Australia.


Located in the beautiful Southern Highlands of NSW, 1.5 hours south-west of Sydney – Wingecarribee Shire Council is working to create and nurture a vibrant community. Wingecarribee Shire covers an area of 2700 square kilometres. This area is known to tourists as the Southern Highlands of New South Wales. This Shire is an important catchment area for water supply to Sydney, Wollongong and the Northern Shoalhaven.

Much of the Shire is located at or above 640 metres above sea level. The main towns are Bowral, Moss Vale, Mittagong and Bundanoon. As well, there are smaller villages including Hill Top, Yerrinbool, Colo Vale, Robertson, Berrima, New Berrima, Exeter, Burrawang, Penrose, Willow Vale, Alpine, Balaclava, Renwick, Wingello, Sutton Forest, Avoca, Fitzroy Falls and Balmoral Village.

The pattern of development is one of small towns and villages, separated by a semi rural landscape and from a planning perspective, Council intends to retain this character of the Shire. The Eastern parts of the Shire are bounded by the Illawarra escarpment and Morton National Park, with some remnant rainforest and heathland.


The North of the Shire is characterised by rugged Eucalypt bushland, with gullies, gorges and sandy soils. This area forms part of the catchment for Sydney’s water supply and three major storage dams (Avon, Nepean and Cordeaux).


The Wollondilly and Wingecarribee Rivers flow through the West of the Shire, through deep sandstone valleys and much of this area forms part of the catchment for Warragamba Dam. The South of the Shire is bounded by Uringalla Creek and includes the villages of Bundanoon, Wingello and Penrose. This area is a sandstone plateau dissected by deep gorges.

The original brief from Wingecarribee Shire Council was to improve the soil health and turf cover of 10 sportsfields. Product needs to be fairly light (compared to sand) and easy to spread. A sand and soil component is required to fill and level the area. An organic component is required to provide nutrients, improve water holding capacity and assist with turf growth.



Wingecarribee Shire covers an area of 2,700 square kilometres that is typically referred to as the Southern Highlands. Located midway between Sydney and Canberra off the Hume Highway.

Wingecarribee Shire is approximately 110 kilometres southwest of the Sydney CBD and is part of regional Capital Country and to some extent can be considered part of the Southern Tablelands.

GO Compost can be incorporated into both turf underlays and topdressing mixes to improve turf health and performance. Turf requires large amounts of water and nutrients, particularly when used in amenities such as sports fields and parks.


Unfavourable environmental conditions can hamper growth and leave grass stressed, which in turn leads to disease.


Using GO Compost in turf mixes increases organic matter which can assist by:


Increasing water holding capacity – Trials have found that organic matter can hold up to twice its weight or more in water. Top dressing with organic materials keeps moisture at the soil surface, giving access of water to roots and reducing water repellency in soils.

Provides nutrients – Adding compost to mixes increases availability of the major nutrients and micro nutrients such as iron, manganese, copper and zinc. It can also assist with the availability of phosphorus, reducing the need for artificial fertilisers.

Improves resilience – Compost contains humic substances, provides growth regulators and stimulates microbial activity. This can lead to enhanced turf grass tolerance to environmental stresses such as temperature and UV radiation.
