ALERT: Coronavirus causes reduced customer support hours  

We regret to inform you that due to the impact of the Coronavirus (COVID-19), we will be reducing the opening hours of our contact centre for the next 1-3 months. Australia Post FlexiSIM customer support office hours will be:

Monday to Friday: 7am - 7pm AEST 

Saturday: Closed

Sunday: Closed

For 14 years we have maintained a 24/7 , 365 day Australian based contact centre. Whilst most other companies moved their contact centre off-shore in response to higher wages and costs, we kept ours in Australia and we are very proud of this and the support we provide to our customers. We request your understanding whilst we weather the impact of COVID-19 and we thank you for your support.
