From Roy Morgan Research:
ALP support is now at 53.5% (down 0.5% points since late October) cf. L-NP on 46.5% (up 0.5% points) on a two-party preferred basis according to the latest Roy Morgan Poll on Federal voting intention conducted over the last two weekends.
The small swing to the L-NP came while Prime Minister Scott Morrison attended the Group of 20 (G20) summit in Rome on October 30/31 and then the United Nations Climate Change Conference of the Parties (COP26) the following week in Glasgow, Scotland.
