Australia's Prime Minister Scott Morrison will on Tuesday front parliament for the first time in three months as he seeks to repair his standing with voters angry by his response to the country's bush fire crisis and a scandal over sports funding.

Morrison secured re-election in May 2019, defying polls that had indicated voters would punish his conservative government for ousting its former leader Malcolm Turnbull in 2018.

Less than nine months after what he described as his "miracle" re-election, Morrison is now unpopular with voters and under pressure from opposition Labor lawmakers.
