Kerry has been trying to secure at least some international support for a potential U.S. strike after accusing the Syrian government of launching a chemical weapons attack.
Australian Foreign Minister Bob Carr's spokesman Patrick Low said Monday that Kerry called last week and that Australia supports the U.S. taking action. He said Kerry didn't ask for military assistance and Australia didn't offer it.
New Zealand Prime Minister John Key said Kerry called Foreign Minister Murray McCully over the weekend and that New Zealand wants to assess all steps taken ahead of a strike before stating its position.
The U.S. doesn't have widespread support internationally for military action. So far, only France has indicated it would join a U.S. strike. The Parliament of key ally Britain last week rejected a vote endorsing military action.
