I have just spoken to Sarah Smith in Perth (coy secretary).
The Altona street office is the registered office for ASX listing. The offices in Sydney have been vacated, (re preceding post on corporate contacts from 2016) and the entire management team are currently based in Burraga. No contact number for that office as yet.
She also mentioned that the quarterly report will be released before the meeting.
Did not give a specific date for the quarterly, so I will have a guess that it will be after Anzac day 26th/27th.
