Opposition Leader Bill Shorten's popularity with voters has taken a tumble, according to the latest Fairfax-Ipsos poll.
The results show since May, Mr Shorten's approval rating has fallen from 42 to 36 per cent, while his disapproval rating rose from 47 to 52 per cent.
The poll, released on Sunday, also revealed Prime Minister Malcolm Turnbull's approval rating fell by three percentage points and his disapproval rating rose three percentage points.
Labor continues to enjoy a two-party preferred lead over the government of 53 to 47 per cent.
The results follow ongoing political arguments about the electricity supply and upcoming same-sex marriage postal survey.
The drawn-out citizenship saga has also featured heavily in federal politics for months, ensnaring senior coalition, Greens and some Labor and independent MPs.
