Mount Isa Pharmacy First owner Leigh Houldsworth said she was concerned about losing a significant amount of stock.
"Not only can't we serve our customers but we've got really high cost and essential items in our refrigerator that we can't transfer to the hospital due to their fridges being full," she said.
"We probably have close to $80,000 worth of stock we're desperately trying to save and it's stuff that's really difficult to get out here so if we lose it, it's really hard to replace."
She said some customers had brought in generators.
"We've transferred our COVID-19 vaccines to the hospital."

Member for Traeger Robbie Katter said the outage was a "big deal".

"If you don't have power in a place like Mount Isa you're in trouble."
