The opinion polls are still bad news for the government. Typical recent poll figures are Coalition 48-ALP 52. Bob Hawke won in 1983 with a 2PP of 53%. The government may try their chances, but it would be a huge risk on current opinion polling.
On the prospects of an early election, the current possibilities are a House-only election or a double dissolution.
(1) House only election. I consider this unlikely because early elections that put the House out of step with the Senate are very rare. The last time there was an early House-only election was in 1963, when PM Menzies went to the poll early to obtain a more workable majority than the 2-seat majority he got in the 1961 election.
(2) Double dissolution. The PM has difficulty with the Senate, partly due to the inability to negotiate, and partly due to the diversity of the crossbench. A double dissolution election could resolve a perceived impasse, but it would be likely to end up with an even more diverse Senate due to the lower quotas for elections.
What cannot happen right now is a House and half-Senate election (the usual kind of election). The writs for a half Senate election cannot be issued more than 12 months before the expiration of the terms of the current Senators. The earliest a half-Senate election can be held in accordance with the Constitution is early August, 2016.
If an early election is being considered, IMO it's going to be a double dissolution election. What are the triggers for a DD election?
