At this stage, it does not look like the Australian government will let us depart Australia for a very long time - until there is an effective vaccine!
So even though I have Easter 2021 off work, I very much doubt we will be making an appearance in Nagoya next Easter if Japan Do 8 takes place!
I am currently in Thailand. Anyone can freely depart Thailand, but entry (and re-entry) is restricted, requiring considerable paperwork, expense, Certificate of Entry, Covid-19 tests, 14 day quarantine in a government approved hotel at your expense, ... So sadly it is difficult to consider a Japan trip at this time.
