"Police will be out in force"- authorities urge Australians not to change plans for Anzac Day.

Australia's national terror threat level is "probable", but law enforcement authorities are sharing one message: This Anzac Day, we should not let fear change our plans. Authorities say there is no specific threat to Anzac Day celebrations this year, adding that Australians "don't accept terrorism as a reason to change" their lifestyles.
