alp (57.5%) surges to lead over l-np (42.5%), page-114

Possibly the discussion at the dinner between Turnbull, Palmer and others was to plan blocking of key budget measures forcing an election for the House of Reps later this year.
The Coalition would lose, Abbott would resign as leader and Turnbull would replace him.
Labor would then get another term in government but this time with a hostile Senate with PUP pulling the strings.
Depending on how things go after that IMO it is likely that the Coalition would win the following election and Turnbull would become PM.
