Our story

Two teachers, a dairy district, and a gamble on olives

After many years of secondary school teaching, Chris and Andrea McCallum decided to learn something new themselves, and planted a small olive grove in Devon North. The locals in this traditional dairying district of Gippsland were very interested in the venture, but sceptical of how successful olive growing would be in this part of the world.

The first planting in 1998 included Corregiola, Frantoio, Hardy’s Mammoth and Manzanillo. More Corregiola, Frantoio, Hardy’s Mammoth and Jumbo Kalamata trees followed in 2000 and 2002. Research into successful varieties in Northern Italy led to Corregiola and Frantoio being chosen as the grove’s primary olives.

The railway track at the top of the Devon Siding logo is a nod to the railway that once ran through the property from Yarram to the historic timber-cutting settlement in the Mullungdung forest.

Pressed locally

The fruit is pressed locally within the Southern Gippsland Olives association.

Finished at the grove

Back at Devon Siding, Chris and Andrea let the oil settle before filtering, bottling, capping and labelling it themselves.
