We currently reside in Australia, so travel across the Tasman with the risk of having to be quarantined for two weeks minimum going both ways is a major deterrent to scheduling future events, as well as the risk of another outbreak preventing or severely limiting events. Any such venture at this stage would not be financially viable, and could even result in a large financial loss.
At present we are holding a limited number of small courses in Australia which is minimising the losses this side of the Tasman, and we hope to remain viable going forward so long as there are no additional limitations forced upon us by COVID outbreaks.
At this stage we none of us can predict the future of this pandemic. Keep in mind that historically no vaccine for such a disease has been developed in less than four years, so we could be looking at this situation continuing for some time yet. Though there are currently three vaccines showing great promise, proving their safety and efficacy could take some time, plus then getting them to mass distribution. Perhaps this time with so many researchers working on the problem we will beat the old record for successfully developing a viable vaccine, here's hoping!
Meantime, keep safe everyone please.
