It comes as fire crews battled a blaze that broke out at an Australian oil refinery which provides ten per cent of the nation's fuel.
The federal government has announced a streamlined border import process for fertiliser as the Middle East conflict continues to put pressure on 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 will 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 impacted.
"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.
"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.
Meanwhile, Trade Minister Don Farrell is travelling to Singapore on Thursday to join Foreign Minister Penny Wong in a bid to guarantee ongoing fuel supplies.
It follows Prime Minister Anthony Albanese's visit to Singapore last week, where he agreed on strengthening energy ties with his counterpart Lawrence Wong.
Singapore provided 26 per cent of Australia's refined fuel imports in 2025, while Australia was the source of 32 per cent by volume of Singapore's LNG imports.
Mr Albanese is in Malaysia where he continues his string of international visits to shore up Australia's fuel supplies.
Malaysia supplies 14 per cent of Australia's diesel, 10 per cent of its petrol and 11 per cent of its jet fuel, and is also the nation's largest provider of crude oil.
Opposition Leader Angus Taylor questioned whether the trip was delivering results for Australians.
"How many more (litres of fuel) has the prime minister generated on his trip through Asia? Is this just a photo opportunity?" he told reporters in the Gold Coast.
"Is this just producing joint statements, or is it going to deliver fuel?"
Mr Taylor said the unprecedented fire in Geelong at one of Australia's two operational oil refineries meant the government had to work even harder "to get more shipments" into the country.
The refinery produces 50 per cent of Victoria's fuel and 10 per cent of Australia's.
Energy Minister Chris Bowen said fuel supplies would be impacted for some time.
