Federal government says Australia's fuel supply is 'solid and secure' as prices climb again

In short:

The federal government is moving to reassure motorists about Australia's fuel supply as the conflict between the United States and Iran re-escalates once again.

Oil prices tipped over $US100 ($143) a barrel this week for the first time since May, with the national average unleaded 91 price at $1.88 per litre on Saturday and diesel at $2.30.

What's next?

The fuel excise discount is due to expire on August 2, having been halved this month to 16 cents per litre.
