Kisnorbo scored for Australia in their recent friendly defeat by South Korea
Leeds United's League One match at Swindon Town on Saturday, 14 November has been postponed due to international call-ups.
Three United players have so far been selected for their countries and under FA rules Leeds have asked for the contest to be re-arranged.
Defenders Rui Marques and Patrick Kisnorbo will represent Angola and Australia respectively.
Keeper Alan Martin has been selected for the Scotland Under-21 squad.
Further Leeds players could also be away that week as centre-back Lubomir Michalik is on standby for Slovakia.
Midifielder Robert Snodgrass hopes to win a call-up for Scotland, whose squad is announced on Thursday, for their clash with Wales, while Wolves loanee striker Sam Vokes could play for the Welsh in that match.
Leeds manager Simon Grayson told the club's website: "League regulations stipulate that a game can be called off if you have three players called up for international duty.
"As it stands we have three called-up and one on stand-by, but there are still some more squads to be announced and it may be that we lose other players or have players placed on stand-by.
"We wanted to make a decision at the earliest opportunity to inform people."
