The Solomons Islands' security pact with China has become an Australian election issue. 

Australia's Opposition is calling it the worst foreign policy failure since World War II.  

It was a major point in last night's first leaders' debate, with Prime Minister Scott Morrison and Labor's Anthony Albanese going head-to-head. 

Australian correspondent Murray Olds told Andrew Dickens the Government is telling voters it's better at national and international security than the Opposition. 

“Clearly this is a big, big problem, having China sign up a deal with a country that New Zealand and Australia have poured a lot of resources into.”
