The Andamooka Progress and Opal Miners Association moved across the road into its new premises last week.
The association moved from a small, cramped space on the north side of Government Road to an office in the Andamooka Community Hall.
"Its quite different from being in a dug out," APOMA's new administrative assistant Heather Hounslow said.
"This room is much cleaner and better lit."
APOMA has been assisted by the Outback Areas Community Development Trust with furniture and fittings.
"We now have a more professional look," Ms Hounslow said.
"People can come in, have a coffee … they can review the minutes of APOMA's meetings and discuss any concerns they might have."
Membership fees were collected at the APOMA barbecue on Sunday.
Fees are $55 for a family, $30 for single people and $17.50 for pensioners.
Residents can renew their membership anytime at the new office.
The new office can also arrange water deliveries and community bus or hall bookings.
We have some exciting projects on the go at present, Ms Hounslow said.
"Arid Lands Botanic Gardens are doing plantings around the town soon,” she said.
“They are targeting the heritage cottages, the cemetery and the town park."
The board are also asking residents to be patient with road re-alignments being conducted by Transport SA over the coming months Ms Hounslow said.
“I just hope this hall doesn't have any ghosts left over from its Marilinga day,” she said
The Andamooka Hall was once the officer's mess at Marilinga Test Base.
It is a magnificent corrugated iron shed and a much-loved public building in Andamooka, which was relocated to the town largely by volunteer labour.
