I had pencilled myself in for Barbados in March ‘23, which is slightly more likely than Australia this year. Having been down under for the victory in 2010/11 I am not in a hurry to go back there and see us lose!
I think booking international sporting events is a big risk. Even if travel is possible will there be capacity crowds? If not then tickets will be even more hard to come by than they usually are in Sydney for example.
