The invitational from the Tonga coach Toutai Kefu comes just a week out from the start of the Western Force's National Rugby Championship season.
Western Force coach Tim Sampson says it will be a very special occasion for his team which also features two Tongans.
"Obviously playing a national team is a huge honour for the club and it is something that we are really looking forward to. It doesn't happen often these days where club plays country," Tim Sampson said.
