International sporting events are a minuscule proportion of the potential economic impacts of Covid-19. Australia's economy has fared much better than America or Europe. Because Australia managed to keep the virus under control. We were not immune, many people have still died from Covid-19. But compared to America and Europe Australia did well. Australia proved restrictions can work as not only did we bring the virus under control after the initial surge in March but we did it again in the state of Victoria after they lost control of quarantine.The Victorian Hotel Quarantine debacle has nothing to do with my post - It is Australia who is costing itself financially by making it difficult to have international sporting events, while also disappointing the public and costing jobs/livelihoods - Yes the point about Aussie citizens and residents being stuck overseas, while the Embassies suggest to apply for crowd funding, sending people to shelters, applying for loans for excessive air fares etc.etc,etc is far from ideal - Anyway we need to hope there is a vaccine in 2021 or 2022 will be rinse and repeat.
The reasons for Victoria's quarantine debacle are fairly well known even if the official inquiry drags on for political reasons. But as far as the TDU is concerned yes it is the 14 day compulsory quarantine which must be the crucial factor. As far as I know horses don't carry the virus and all people who came for the Melbourne cup would have done so well in advance to comply with the quarantine rules. This won't work for riders from Europe who would lose form quickly. Of course I agree wholeheartedly that a vaccine becomes available as soon as possible.
