Drought-stricken farmers desperate for a further cash injection to keep businesses alive will have to wait a little longer as the Morrison government weighs its next move.

Treasurer Josh Frydenberg told reporters "This is a crisis and as one family member said to [him] me before, this is the community's GFC plus some," 

The federal government announced a $100 million package last week.
