Thanks for ur info CaptanC, I shot them an email with my PCCs straight away, but did not either upload or click the "Request Complete" button in my immi account, in case they need new ones. As the matter of fact, my Vietnamese PCC is quite old (from 2013) so I re-applied anyway, should be ready next week. And I tried to ring up GSM Adelaide but the waiting was frustratingly long...I probably will upload the new PCCs to immi account as soon as they are ready. Thanks again mate.
