"To play Samoa first is a tough ask,'' Kearney said. "They are going to have a good team. Ideally, you would have liked to play them at the back end of pool play so you could build momentum. We have to hit the ground running because we don't have time to warm into it. We have to focus on that game because there might not be a back end of the tournament if you don't get it right.
"We will definitely be having a warm-up game. It's just a matter of where and who against. It's what is best for our preparation. I would like to play over in the UK before the tournament. We are working through that at the moment.
"There could also be a possibility of a Prime Minister's XIII against an Australian XIII, like the team they take up to PNG. We're looking at that possibility.''
A detailed programme for the 35-40 players in consideration for the World Cup will be put together and regular contact made with the leadership group.
Decisions will also need to be made around the makeup of Kearney's coaching group, with Tony Kemp's resignation because of allegations of sexual harassment creating a vacancy. Kemp was part of the high performance team and also acted as team manager.
Assistant coach Tony Iro stepped into the manager's role for the Anzac test but will not be able to do both jobs at the World Cup and Kearney is reviewing his options.
He leaned on former Australia coach Wayne Bennett as a mentor for the 2008 World Cup campaign when they claimed their first world title and has used him as a sounding board since.
"Having someone like Wayne involved, because it was my first year as a head coach, gave me and the lads confidence,'' Kearney said. ``I am now five years more experienced but that might be something we look at - but not Wayne.
"Tony Iro might take up the manager's role now so I will need some help on the coaching front. We will look at that over the next week or two.''
