The Finance Minister is confident she hasn't jumped the gun with her fuel relief package. 

The Government's unveiled a temporary $50 weekly tax credit for about 143 thousand eligible lower-income families with children. 

It will continue for a year, or until the price of 91 drops below $3 a litre for four weeks in a row. 

Nicola Willis told Mike Hosking she has to prepare for a range of scenarios. 

She says the conflict could be prolonged, and the supply chain disruption that's causing prices to rise could continue for some time. 

Willis says she’s focusing on securing supply rather than providing support for businesses facing rising fuel prices. 

When it comes to helping businesses, the Government is changing fuel rules so importers can bring in fuel refined to Australian standards. 

She told Hosking it's essential the transport, manufacturing and agriculture sectors have enough fuel to keep going. 

Willis says it would be wrong to artificially push down the price of diesel when —if the worst-case scenario plays out— we could be having to preserve our diesel supply.
