Message from David Hamer – Managing Director
Coronavirus (COVID-19)
In response to COVID-19, we appreciate that NDIS providers who need to be verified are likely to come under increasing pressure with costs. So, to assist NDIS providers become verified, we’ve made the process of becoming verified easier and have significantly reduced the cost of Verification audits to $825 (exc GST) from 16 March until further notice. To have your verification audit completed, please send your Initial Scope of Audit to ndis@hdaau.com.au. We’ll then get in contact, send you an agreement, and complete your verification. If you need a provisional certification audit completed, please contact us for a reduced cost proposal.
We’re monitoring the COVID-19 situation very closely and putting in place several measures to protect service participants, staff, assessors, and others during this pandemic. Because we’re internationally accredited by JAS-ANZ to complete remote computer-based audits [IAF MD4:2018 – For the Use of Information and Communication Technology (ICT) for Auditing/Assessment Purposes], we’re formally able to complete assessments remotely.
