An election is due for good reasons. It will end an incompetent government that is further compromised by its alliance with the Greens and also heavily influenced by the independents so one person can have hugely disproportionate influence to make the system very poorly governed.
While the opposition has not outlined a comprehensive policy setting, the current government has shown its wasteful character and poor policy making and governing.
So, one is known to be poor and the other is potentially unknown poor but also potentially better.
In such circumstances, I think the majority of voters are likely to see a change of government.
There might be some tears in the minority of voters, but it will be good for the nation should an election be had sooner rather than later.
It is not a perfect world and it is unreasonable to expect the opposition be perfect.
One has to choose the lesser between two devils. On balance, the opposition seems a better bet.
