The Olive Centre specialises in supplying Equipment & machinery for the needs of olive growers in Australia and other major Olive Producing Countries.

These Trees were purchased from Australis Plants (formally known as "Olives Australia").
DNA matching the Frantoio & Correggiola of Tuscany and Italy had been confirmed by Olives Australia at time of purchase. Whilst Correggiola and Frantoio are from the same varietal population (family) there are some genetic differences. To read more on this topic please visit Australis Plants Olive page HERE .

Barkly has presented itself with premium growing conditions for olives, with an elevation of 270 m (886 ft) and extreme climatic changes from blistering temperatures +40°C in summer down to a chilling sub-zero avg. of -4°C in winter.

  • Chill factor being an important requirement for the fruit-set
  • Heat being important for olive trees in general, due to their countries of origin.

Company Profile

The business is now producing premium grade Extra Virgin Olive Oil and Rosemary for the Australian and export markets. The olives have been planted extensively throughout the property as commercial trees, windbreaks and shade trees for dams and to aid in erosion control. The Rosemary has been planted as companion plants throughout the property. The Olive trees were planted in the late 1990s and are now commercially viable.

The varieties, Frantoio and Correggiola will predominate, as these varieties are known for producing extremely high quality extra virgin olive oil. These will be marketed as boutique olive oil sold in small, shapely dark bottles to aid in shelf life and presentation.

The extraction process is carried out by the professionals at " Grampians Olive Co , home to the historic Toscana Olive Plantation" in Laharum Victoria, Australia.

The Rosemary has been planted in one major bed and as companion plants around the property for the olive trees.

The Rosemary will be available in fresh form as well as used in some of our infused olive oils.

Our Origins

Growth & Maintenance
Harvest & Olive Oil
Land acquired.
Business commences March 1998. Soil preparation begins, employing the "TATURA" method, whilst obtaining a certificate in small business management utilizing "New Enterprise Incentive Scheme (NEIS)". This allowed the development of our business plan with access to mentors and the NEIS business networks. Restored damaged dam.
Tree planting, staking and protective surrounds made from soft drink bottles began at the end of 1998… the planting continues with every tree being watered by hand. A rabbit infestation has diverted us from our goals for now and the warrens are being taken care of by a government incentive named "Rabbit Busters". Meanwhile the bulldozer has returned to rip new lines for the olives.
Continuing to water by hand as trees establish. Applications to Pyrenees Shire Council for the erection of a shed and the renaming of "Government Road" to "Treowen Lane" approved. Construction of top dam begins. Attention now turns to the preparation for the shed building site whilst repairing the various erosion sites. Small orchard established with apples, pears, cherries, peaches, nectarines and plums.
Stakes and protective surrounds are removed from the well established trees and some replanting due to local fauna interference takes place. The ongoing battle against suckers starts and hand watering continues until winter 2004.
Much pruning has taken place over the previous 5 years as the trees have reached a maturity for bearing excellent fruit. 2015 First harvest with an award winning Frantoio/Correggiola blend receiving a Bronze Medallion during the Annual Hunter Valley Olive Show.

Both the Frantoio and the Correggiola trees supplied by Olives Australia have been DNA confirmed as matching the Frantoio and Correggiola of Tuscany, Italy. Whilst Correggiola and Frantoio are from the same varietal population ("family") there are some genetic differences. This influences the difference in palette and aroma as cited above in both olive oil descriptions.

The composition of olive oil varies with the cultivar, altitude, time of harvest and extraction process.
Being located in the Barkly/Moonambel district amongst the foothills of the Pyrenees ranges has proven ideal for these cultivars.

We select the best trees for hand-harvesting then process our fruit within in 36 hours, ensuring the free fatty acids remain low. Free acidity is an important parameter that defines the quality of olive oil and is defined as a percentage as grams of free fatty acids (expressed as oleic acid) in 100 g of oil. Extra-Virgin olive oil must feature a free acidity lower than 0.8%. Please refer Modern Olives Laboratory Services report .
Both our Frantoio (AU 17/0454/1) and Correggiola (AU 17/0454/2) have a Free Fatty Acid content of 0.2%

Fresh Rosemary

Rosmarinus Officinalis

Our primary use for Rosemary will be for some of our infused Olive Oils.
We do however offer this up for supply to the local culinary industry.



2017:– we have picked two types of our olives:

  • Correggiola
  • Frantoio

These particular Italian olive varieties are known for their ability to produce high quality oils.
To ensure a premium oil, the trees need to be tended to in the following manner:

Leaving the irrigation of the trees to precipitation, we have made them hardier; and not so susceptible to droughts. This means that the trees have taken a lot longer to reach maturity other than an irrigated grove.
It also means that we get less fruit per tree, but the oil is more intense in flavour and its aromatic complexities.

Olive trees produce vigorous growth and if not tended to will allow many branch formations that will produce an abundant fruit of a lower quality, therefore we need to prune the trees in a manner of opening the centre, allowing penetration of air and sunlight through the canopy (Open Vase System).
We remove all suckers which grow at the base of the trees including air shoots and crossover branches in the canopy. By opening the tree like this we make them less vulnerable to diseases such as black sooty mould and scale insect.

Olive Oil Health Benefits

Olive Oil Diet Reduces Risk of Type 2 Diabetes

Traditionally a low-fat diet has been prescribed to prevent various diseases such as heart disease and diabetes. While studies have shown that high fat diets may increase the risk of certain diseases such as cancer and diabetes, it appears that it is the type of fat that counts rather than the amount of fat. We now know that a diet rich in mono-unsaturated fats such as the ones found in olive oil, nuts and seeds actually protects from many of these chronic diseases.
A study published in the scientific journal Diabetes Care showed that a Mediterranean style diet rich in olive oil reduced the risk of type II diabetes by almost 50 percent compared to a low fat diet. Type II diabetes is the most common and preventable form of diabetes.

Olive Oil May Protect from Depression

It is common knowledge that olive oil and the Mediterranean diet confer a multitude of health benefits. But what about emotional health benefits?
According to Spanish researchers from the University of Navarra and Las Palmas de Gran Canaria, a diet rich in olive oil can protect from mental illness.
Researchers recently discovered that a higher intake of olive oil and polyunsaturated fats found in fatty fish and vegetable oils was associated with a lower risk of depression.
The findings suggested that cardiovascular disease and depression may share some common mechanisms related to one's diet.

Olive Oil Keeps the Heart Young

A diet rich in olive oil may actually be able to slow down the aging of the heart.
It is a known fact that as we grow older the heart also goes through a normal aging process. The arteries may not function as well as they did and this can lead to a number of health problems. However, in a recent study, Spanish researchers discovered that a diet rich in olive oil or other mono-unsaturated fats could improve the arterial function of elderly individuals.

Olive Oil Fights Osteoporosis

Osteoporosis is a disease characterized by a decrease in bone mass, which in turn causes the architecture of bone tissue to become fragile. This can then increase the possibly of fractures, making even the slightest of knocks potentially fatal for sufferers.
Olive oil supplementation was found to positively affect the thickness of bones. Olive oil will not be the only solution in the continuing fight against post-menopausal osteoporosis, however scientists have concluded that it is a very promising candidate for future treatments of the disease.

Olive Oil Might Help Prevent Strokes

Older individuals who consume olive oil daily may be able to protect themselves from a stroke, according to a new study from France published in the online issue of Neurology.
Researchers gathered information from the medical records of 7,625 individuals over the age of 65 from three cities in France: Bordeaux, Dijon and Montpellier. None of the participants had a history of stroke. They then categorized the individuals into three groups based on their olive oil consumption. The researchers noted that the participants used mostly extra virgin olive oil, as that is what is usually available in France.
After 5 years there were 148 strokes. The results showed that the “intensive” users of olive oil, those that used for both cooking and dressings had a 41 percent lower risk of stroke compared to those that did not use olive oil at all. These results were noted even after considering weight, diet, physical activity and other risk factors.

Olive Oil Found to Help Prevent Skin Cancer

Another recent study found that olive oil, along with other components of a Mediterranean diet, may contribute to the prevention of malignant melanoma. The most dangerous type of skin cancer may be slowed down by consumption of olive oil, which is rich in antioxidants, the researchers found.
The use of sunscreen remains the best way to prevent sunburn and shield the skin from the harmful effects of the sun’s UVA and UVB rays. However, “Going Greek” and consuming olive oil and other Mediterranean food staples, could help counter the oxidizing effect of the sun.
Only three in every 100,000 residents of countries in the Mediterranean develop any form of skin cancer. The figure is low, especially when considering the warm climate in the region. In Australia, the figure is 50 in every 100,000 residents.
