I don't think Australia will be holding many (if any) competitions in the future. Being an island nation it's possible to eliminate coronavirus and cut international arrivals to a level where there is <1 month of lockdowns/restrictions per year for outbreaks. You could live as COVID-19 did not exist (with the exception of international travel) for all but maybe 1 month of a year. However this not what is going to happen in the future. Once 70% of the population is vaccinated the government is going to let the virus go in Australia. From a quick search about 92% of the UK population have coronavirus antibodies. The UK is having about 500 cases per 1,000,000 people in summer. Temperature is one of the key factors in number of COVID-19 cases (The colder it is the more cases there are normally). I am not expecting Australia to have many (if any) competitions in the future. There is a small possibility that competitions could occur in the summer months of January and February.
