URGENT HELP REQUESTED - approved eTa cancelled and I am travelling tonight

[jdrobbo]

Hello,
I am an Australian in Hong Kong who has just received a do not reply email advising that my previously approved eTa is now cancelled. I am travelling in 6 hours. There is no reason specified in the email I have received just a blank bullet point.
I cannot get through to immigration by phone.
Please help!
Thanks

Implementation of ETA has been delayed by six months. You don't need ETA to travel tomorrow.
