Our story

From one pallet to a regional operation.

David and Lorna Skewes started Colonial Chemicals in 1993 with a typewriter, an invoice book and a belief that country customers deserved local knowledge and dependable supply.

That first order became a family enterprise manufacturing in the Tamworth region and dispatching essential products thousands of kilometres across regional NSW each year.
