AFL chief executive Andrew Demetriou has played down the fact that several pitch invasions occurred during the First Test of the International Rules series clash between Ireland and Australia at Pearse Stadium in Galway on Saturday night.Although Demetriou was not endorsing the pitch invaders - which included 'Superman', a 'sheik', 'Warwick Capper' and a male streaker during half-time - he said the Aussies simply needed to accept that they were in another country and some things were going to be different."We're guests in the country and we accept what happens here and we play by the rules here and it's never been an issue before and I'm sure it won't be an issue going forward," Demetriou said after Australia's eight-point loss."We're in Ireland and it's pretty traditional here and it's not something that we have in our country and in our games, but the crowd was pretty pleasant and they're used to it, but we're glad it doesn't happen every week in our game."As I said, we're playing in Ireland and we accept some of the things and it was good being in Galway for the first time and I think the crowd enjoyed themselves.Demetriou said Croke Park would have no such pitch invasion issues."I don't think it'll happen at Croke Park, because we're blessed with better security at Croke Park and it was the first time we've come to Galway and we said it was good to come to Galway and get 40,00-odd people and it's just a bit different here," Demetriou said."We are playing in Galway for the first time and it's good that we've come here and we're pleased that we've done it and Galway has been a buzz all week and I hope we can come back again."Demetriou said he was proud of the AFL's measures to protect its players at AFL venues."I think it reinforces in our mind why some of the things we do - we're pretty proud of and we go to great lengths at all of our venues about security and pitch invasions and we'll continue to do that and when you're not at home and not in charge of the venue and you're not in charge of security - and we don't employ the people here - we have to sometimes put up with things that we normally don't have to put up with in Australia," Demetriou said.But Demetriou said the invasions were something the Gaelic Atheletic Asccocation needed to address."It's something for the GAA to look at … we certainly know how we do it in Australia and we'll continue to enforce our security, particularly when it's in our home-and-away season or when we have our next International Rules series," Demetriou said.As for Australian coach Kevin Sheedy's take on the pitch invaders?"(They brought back the) Memories … thought I was back to the '70s again," said Sheedy.
