The rugby team were to play the Wallabies on July 4th.
Ireland's summer tour of Australia is officially off.
Andy Farrell's men were due to play the Wallabies in Brisbane on July 4th and Sydney a week later, but these matches have been postponed by World Rugby.
Meanwhile, the European Champions Cup could have 24 teams on a one-off basis from next year, with teams from the Pro 14, England and France contributing 8 teams each.
That would allow Connacht a place in the competition.
