As the leader of the National Party said just yesterday, and it was a very good interview:

… the big message for every Australian is don't panic. The suppliers are there.

…   …   …

We all have a role to play in that … stick to our normal daily operations and schedules and don't think that we have to always keep topping up.

Not to be outdone, Senator Jonno Duniam today, when asked about refinery issues and energy security, said:

… I do accept that successive governments have let Australians down … It hasn't just happened over the last four years. This is decades in the making …

And, indeed, there were six refineries when government changed in 2013. When they left office, there were two. So two-thirds of them shut down.
