OCONNORS RAP reaches implementation phase

I’m excited to share with you that we have had our reconciliation action plan (RAP) formally endorses by Reconciliation Australia as a #Reflect RAP.  
 Reconciliation Australia now officially accredits OConnors RAP and recognises us as a member of the RAP network.
We now commence our all-important implementation phase with a commitment to tangible actions, such as increasing Aboriginal and Torres Strait Islander employment, participating in external events and raising cultural awareness within our organisation. 
Our RAP is an aligned with our family culture and companies’ core values. It is becoming part of One O’Connors and is supported at all levels of our organisation.  Our vision is that through our actions, we can contribute to our nation’s shared goal of a reconciled, just and equitable Australia. Please find attached a copy of our reconciliation action plan.
I would like to thank all those involved in driving us to this stage, in particular Alberto O’Connor, Mark Liddy, Tammy Giles, Vincent Campagnale, Sarah Gorman, Clare Tippins, Jarrod Varley, Elizabeth O’Connor,  Dylan Cooper and James Tedmanson.
