No surprise Abbott wants his say: Keenan

Australia's justice minister says former prime minister Tony Abbott is entitled to share his views on national affairs and it won't upset the government.

It is no surprise that Tony Abbott wants his "two-cents worth" on national and international affairs, Justice Minister Michael Keenan says.

The former prime minister has called for military action in Syria in contrast to Prime Minister Malcolm Turnbull's emphasis on an international approach to tackling terrorism and the deadly attacks in Paris.

"I don't think any Australian should be surprised that Tony Abbott, whilst he remains in parliament, will make a significant contribution to national debate and I don't think we should be concerned about that as a government," Mr Keenan told Sky News on Sunday.
