XPT is right with Para 3)
Any time an election is announced in Oz lots of people immediately stop having holidays, even weekends away (ask any B&B owner) or spending on big ticket items.
Ask those same people if they intend to resume their spending ways if the Libs get in and they say yes. What if labor gets in, yes again.
There's no figuring it out, just how it's been for years.
So, get some cheap seats now and avoid the rush on 3rd July.
