THE IRISH team to face Australia in the Virgin Australia International Rules Series has been hit with a blow just days out from the first Test, with several players falling ill.

Adelaide Oval will stage a match on Sunday, with the next Test at Perth Stadium on Saturday week.

Ireland's team physiotherapist Enda McGinley told BBC Northern Ireland those affected had been isolated to avoid any spread of the illness, which had caused vomiting.

"Three or four others, along with myself, have been affected by one of those problems that is associated with long-haul flights," McGinley said.

"Around 48-72 hours after we arrived, some of us starting coming down with a bug.

"All the steps are being taken to limit its spread within the camp, because it's obviously far from ideal with the Test match coming up this Sunday.

"Players that are affected have been given single rooms and everybody has individual water bottles, so all the steps that can be taken, are being taken."

Ireland expects to have everyone fit by Sunday.

"We are fairly confident that nobody will be having to sit out at this stage," McGinley said.

"Hopefully we will get over it and limit its spread, as it's one of those things that can affect touring parties.

"This year's squad is quite limited. We've only taken 23 players, which isn't a lot, so we can't afford to be missing anybody, especially given the conditions."

Australia's Scott Pendlebury told reporters the heat would suit his side.

"It's good to know the Irish have been a bit sick, and it's good to know that it's going to be 34 degrees on Sunday, so it will be nice and hot, and we’re looking forward to playing in the sweltering conditions," Pendlebury said.

The game will start at 3.40pm ACDT.
