It appears Tony Abbott’s post-budget popularity was short-lived, with Opposition Leader Bill Shorten reclaiming the lead as preferred prime minister by one point in the latest Fairfax-Ipsos poll.

The poll shows the government has taken a hit over the worsening housing affordability crisis and its refusal to grant a conscience vote on same-sex marriage.

In a two-party preferred vote, Labor lead the Coalition 53 per cent to 47 per cent.

Labor’s primary vote continued to languish at 37 per cent, up two points since May.

But the Opposition’s two-party preferred result was boosted by an improving Greens primary vote of 14 per cent – up one point since May.

The Liberal Party dropped three percentage points to 40 per cent.

The poll revealed 68 per cent of voters disagreed with Mr Abbott’s refusal to legalise same-sex marriage. The PM continued to deny a formal party-room discussion about marriage equality, in the hope that the issue would never come to a vote.

When pollsters were asked whether housing was affordable to prospective first home-buyers, just 29 per cent of capital city residents said it was compared to 69 per cent who disagreed.

Fairfax Media reported on Monday the Property Council had made a submission to the government’s tax white paper process, calling for an end to stamp duty on housing which had “haemorrhaged” in recent years, dramatically adding to the purchase prices of homes.

It said the cost of stamp duty had exploded by 795 per cent and 749 per cent respectively in Melbourne and Sydney during the past 20 years.

An immediate post-budget survey in May had the two major parties level-pegging on 50/50, Fairfax reported.

The nationwide phone-poll was taken from June 11-13 and was based on responses of 1401 adults. It had a margin of error of plus or minus 2.6 per cent.
