Australian Prime Minister Tony Abbott has used a landmark address to the National Press Club on Monday to warn his coalition government against "infighting".

Speaking in front of the NPC for the first time since taking office in September 2013, Abbott was defiant in defending his government and issued a subtle message in an attempt to end speculation regarding his future.

Following more lamentable polling results and the likelihood that yet another coalition government would be toppled at state level following elections in Queensland over the weekend, rumors have continued to mount regarding Abbott's position.
