Australia has exceptions allowing for you to travel out if you get permission based on living outside the country etc. I know a few that will travel as soon as Thailand allows.
For people like me with over 100 staff I need to get back to make sure everything can be ready to reopen. Dealing with staff remote has been difficult to say the least.
FYI from what I have seen the Australian Lockdown allows for people to fly out of Australia with permission (Must seek approval?) if your normal place of residence is and or your family are located outside the country. I know of people in Australia planning to go back in May if Thailand opens up.
Currently the official word i have been given is that May 10th people with Permission to work in Thailand will be able to re enter but must pay for 14 days in a hotel first before being released into Thailand.
I have family and friends that need me in Thailand but currently no way for me to get back to support them. It's a horrible feeling. And i am here in the USA... I dont belong here (I am Australian)
