Tony Abbott came to power as opposition leader by standing up to the climate change fraud that the coalition was set to endorse at the time.

He is already publically committed to abolishing it as quickly as possible and he will go back to the people for a mandate on that specific issue if he has to to do it.
Here is another FR post about mobs screaming against Abbott about his anti-immigration stance. Also confusion about the meaning of Liberal in the Australian political context.
