New Australian Prime Minister Malcolm Turnbull promised to focus on stability and improving a faltering economy as the public woke up on Tuesday to their fourth leader in two years.
The Liberal Party voted in a secret ballot late on Monday to oust Tony Abbott as the leader of the senior party in a ruling conservative coalition in favour of Turnbull, a multi-millionaire former tech entrepreneur who is popular with the electorate
"I'm filled with optimism and we will be setting out in the weeks ahead ...more of those foundations that will ensure our prosperity in the years ahead," Turnbull told reporters as he headed to parliament on Tuesday before being sworn in.
Abbott was deposed barely two years into his three-year term after months of opinion polls that showed his popularity with the public near rock bottom as Australia's $1.5 trillion economy struggles to cope with the end of a once-in-a-century mining boom
Turnbull had previously been unpalatable to his party's right wing because of his progressive views on climate change, same-sex marriage and making Australia a republic.
However, Abbott's dismal performance and over-reliance on slogans to sell his major policies, including a hardline approach to refugees, wore down internal opposition to Turnbull.
