What I find really strange, unless my info is incorrect, the returning residents to Aus are tested for the virus and declared free, but when tested here prove to be positive. So is it the standard of testing being carried out, or are those certificates false ??
Our hard border is being relaxed just a little but NSW & VIC out of bounds., and our premier has not agreed to have our border opened unlike all the other states in time for Christmas. The vaccine developed from the Uni QLD looks really promising, going to stage 3 testing, and if all O.K. , should start to be rolled out mid March 2021. I don't know about anyone else, my feet are so itchy, can't wait to pack my bags and go wandering Mentally I feel as though I am locked up in jail. I must have been a gypsy in a previous life, I need to travel, it feeds my heart, my soul and my mind. Don't get me wrong I love my piece of paradise but its a big world out there and I want and need to experience it all.
