Noeleen Johnston and Leonie Gehring were able to revive the woman after they immediately started CPR.
Mrs Johnston said first aid training they completed last year meant she and Mrs Gehring had the knowledge and skills to help the woman.
‘I was amazed at how calm and collected we both were during the emergency, and I believe it was due to the training we received,’ she said.
The customer service officers were given a special commendation by St John Ambulance for their efforts.
St John Ambulance deputy chief executive Anthony Smith said the goal of the organisation was to have one person in each household trained in first aid.
‘The first 10 minutes after an incident are most crucial and it is critical that after the call for an ambulance is made, you keep the patient’s airway clear and start CPR if the person is not breathing, as has happened in this instance,’ he said.
