As the festive season approaches, Sonder would like to remind stakeholders that our offices will be closed for 2 weeks during the New Year period.

Our offices will close 5 pm Tuesday 21 December 2021 and will reopen 9 am Thursday 6 January 2022

Clients referred to Sonder or our headspace Centres (Adelaide, Edinburgh North, Marion & Onkaparinga) during this period must be aware that they may not be contacted by Sonder until after Thursday 6 January 2022.

Throughout this period, general practices can continue to send mental health referrals for Sonder’s metropolitan programs to Adelaide PHN’s Central Referral Unit (Via Secure Messaging – HealthLink, EDI: adphncru or ReferralNet/Argus, ID: CRU)

Regional-based general practices can also continue to send mental health referrals for Sonder’s Gawler-Barossa programs directly to Sonder via fax (08) 8252 9433 or email

While some of our services take a small break over this period, a number of our services remain operational (including public holidays):
