Poll shows key WA seats on knife-edge

The Liberal party is in danger of losing some of its prized seats in Perth on Saturday, with election-eve polling showing Labor is narrowing the gap .

A YouGov/Galaxy poll in The West Australian newspaper on Friday indicates Labor's Hannah Beazley - the daughter of former Labor leader Kim - is now neck and neck with the Liberals' Steve Irons in Swan.

The poll points to a fall in the primary vote for Mr Irons.

Aged Care Minister Ken Wyatt is in danger in Hasluck with the two-party preferred vote on 50-50, while Stirling - held by retiring minister Michael Keenan - is also on a knife-edge.

Attorney-General Christian Porter is in a marginally better position in Pearce on 51-49, and is expected to scrape through as his primary vote has improved slightly.

The poll also shows the Liberals probably won't win back Cowan from Labor's Anne Aly who is sitting on 53-47 on a two-party preferred basis.
