Wong’s Palestine call has been criticised as ‘a win for terrorists’ by the Coalition, page-186

Two State Solution is her personal view or ALP policy?

That's ALP policy.
It used to be Coalition policy too.
You may recall that six former Australian Prime Ministers penned a letter recently which included a reaffirmation.
The Coalition under Dutton might be saying that now is not the time to call for a two state solution.
Apparently Wong reiterated the call with provisos about hostage release and Hamas not having influence over the region.
As we know Hamas and the current Israeli government don't want a two state solution.
The current Prime Minister of Israel, Netanyahu often being cited as previously propping up Hamas to stymie a two state solution.
