Australian farmers will receive fertiliser faster as border processes for imports will be streamlined just as sowing season begins.
The federal government announced the measure, in consultation with Fertilizer Australia, as the Middle East conflict continues to put pressure on fertiliser and fuel supplies.
Sixty per cent of the supply of urea to Australia for fertiliser travels through the Strait of Hormuz, which has remained closed since US-Israeli strikes launched on Iran in February.
Agriculture Minister Julie Collins said the changes would reduce costs, reduce port clearance times, lower administrative burdens and ensure the safety of fertiliser prior to shipping.
She said strict biosecurity standards will not be affected.
"There's enough fertiliser in Australia today and on its way on the water in terms of the initial planting season," Ms Collins told Sky News on Thursday.
"But this is about longer-term supplies because of the unpredictability and we don't know how long this is going to go."
The changes include certification from an authorised inspector offshore that the goods are free of biosecurity risk for all imports and a requirement for importers using higher-risk pathways to provide a bagged sample for prior inspection.
