Established in 1892, Whelan the Wrecker is a household name in Melbourne, Victoria.

Our commitment to a practical Indigenous engagement strategy led to an agreement with 100% Aboriginal owned Mallard Contracting for the creation of Delta Mallard in 2015. Since it was established in 2011, Mallard Contracting has been focused on developing the skills of Aboriginal youth through the provision of turnkey solutions to clients across the mining and resources sector. In turn, Delta Group has been able to learn and apply valuable cultural insights as well as offering Indigenous workers greater scope for developing their individual career pathways.
