A devastated wife has spoken out after a father-of-four has spent the week fighting for life after being mowed down outside his home in Melbourne's south-east.

Father-of-four Rayden is in an induced coma after being struck by a driver outside his Clyde North home early on Sunday morning.

The brutal hit-and-run knocked Rayden unconscious, causing a brain injury.

For almost a week, Courtney Storm has barely left her husband's side, calling him "the best dad in the world".

"So supportive, [he] really will put everyone before himself," she told 9News.

"Everyone just loves him. I just don't think I could find someone to say a bad word about him. Trouble doesn't surround him. It doesn't follow him," Courtney said.

The 29-year-old had just returned from a night celebrating his dad's engagement.

Someone in a dark-coloured car drove past, hurling abuse before making a U-turn and striking Rayden.

His loved ones rushed to help, but the car sped off.

"We'd had a really good night, really happy, was laughing with everyone," Courtney said.

"He'd only stepped out for maybe five [or] 10 minutes when it happened."

Detectives are still trying to track down the car, and Courtney says her family did not recognise the driver or passenger, and believes it was a random attack.

"Rayden is not a vindictive person. He will always extend a hand of forgiveness to those who have done things wrong to him," she said.

"He will be in for a long recovery, but outside of that, I don't really know what that looks like or how everything will be."

Donald Trump has followed through on his threat to hit pharmaceuticals entering the US with tariffs, and Australia has been slapped with the highest charge, but Australia's largest manufacturer is expected to dodge the costs.

The US president has imposed a 100 per cent tariff on some pharmaceuticals manufactured outside the US, potentially dealing a heavy blow to one of Australia's biggest exports to the country.

Trump signed the order overnight, but it won't take effect for some months.

Pharmaceuticals are one of Australia's biggest exports to the US, amounting to about $1.6 billion in 2023-24.

The bulk of the sector's value comes from one company, CSL, a major producer of blood plasma products based in Melbourne.

Given that CSL already have a facility in the US, there is confidence it will be exempt from the incoming costs.

The tariff do not yet apply to generic drugs, and there are carve-outs for companies that manufacture their products or intend to in the US.

Instead, the target of the tariffs is firmly on patient drugs that are produced outside the US in an effort to pressure foreign manufacturers to move their production to the US and negotiate agreements to sell their medicines directly to Americans.

The long-anticipated levies will take effect for large drugmakers later this summer, following a 120-day implementation period, a senior administration official told reporters. Smaller companies, by contrast, will get 180 days before the tariffs kick in.

"We expect the lion's share of the world's patented pharmaceuticals to be building" in the US by then, the senior official said. "They've had plenty of warning and we are going forward with it."

The new order includes a series of exemptions from the 100 per cent tariff, including for any company that strikes a deal to join Trump's "Most Favoured Nation" initiative.

Drugmakers that agree to move their production to the US will also get their tariff cut to 20 per cent in exchange.

But even without taking those steps, many foreign drugmakers may end up avoiding the hefty tariff because of broader trade deals that several countries have already made with the Trump administration.

Companies in the European Union, Japan, South Korea, Liechtenstein and Switzerland will only be subject to a pre-existing 15 per cent tariff, while UK companies face just a 10 per cent tariff.

Australian exports are subject to a baseline 10 per cent tariff, but despite pre-existing free trade agreements with the US, none have been struck with Trump over pharmaceuticals.

Australia's Pharmaceutical Benefits Scheme has also been a target of ire among Trump's trade advisors.

The senior official declined to say how many companies would be hit by the 100 per cent tariff.

"It's really focused on a lot of deals that have already been made with companies who might be making in Australia, might be making in Austria, might be making in France or other places," US Trade Representative Jamieson Greer said.

"We have spent the past year hammering out deals with a lot of these companies to make sure they're building in America, which they are."

Meanwhile, Health Minister Mark Butler criticised the move, urging the US to reverse the tariffs.

"This is the wrong decision by a partner of a successful free trade agreement that has endured for more than 20 years," Butler said.

"We want the US administration to think again and to reverse this decision."

The minister reassured that the tariffs will not have an impact on pharmaceutical prices to customers here in Australia.

The new drug tariffs would represent an initial step toward Trump's pledge to reconstruct his aggressive trade strategy after the Supreme Court ruled in February that some of his most significant and far-reaching tariffs were unconstitutional.

Until now, many of the tariffs that Trump has levied on other countries have excluded prescription drugs.

The administration has already negotiated deals with more than a dozen drug companies to sell certain medications directly to consumers as part of a "Most Favoured Nation" pricing initiative aimed at lowering drug prices.

As part of those deals, the drug makers escape tariffs for three years in exchange for increased manufacturing investment in the US.

The initiative includes selling medications directly to consumers on TrumpRx, but that measure only covers a limited number of drugs so far, many of which have generic alternatives that can be found cheaper elsewhere.

Milk producers have asked Australian supermarkets to lift the price of homebrand milk to help dairy companies struggling with double fuel and fertiliser hikes.

The dairy sector is urging Coles and Woolworths to increase the shelf cost of generic milk by at least 30 cents per litre as the dual shortage tightens its grip on farmers.

eastAUSmilk president Tim Bale said he was waiting for a response after approaching the grocery giants about the price change, which would allow Australian milk producers to do the same and remain competitive.

"We need the generic milk to rise so other brands can rise, ensuring some goes to the farmers," Bale told nine.com.au.

"Farmers need [a lift] of 10 to 15 per cent."

A two-litre bottle of Woolworths full cream milk currently costs $3.20.

The Coles-branded full cream milk is the same price, equating to $1.60 per litre.

Nine.com.au has contacted Coles and Woolworths for comment.

Milk processers have called for the same change to cushion the blow of high diesel prices and fertiliser shortages.

The Middle East, known for being one of the world's most dominant suppliers of oil, also supplies up to 45 per cent of the world's urea.

Urea is the most commonly used nitrogen fertiliser that promotes high crop yields and is used for wheat and vegetables. 

"The cost of urea has gone from $800 to $1800 in the past month. Price increases of this level have never happened before," Bale said.

"Fuel and fertiliser are two major input costs for dairy farmers and cost increases of this magnitude cannot be absorbed by dairy farmers.

"Farmers will cut back production or exit the industry over the coming months if something isn't done immediately."

Australian milk suppliers are also facing an increase in the cost of milk bottles and lids due to a domestic resin shortage.

Nick's Food, Milk and More general manager Nick Viropoulos received a letter from his milk supplier on Wednesday, advising him the cost of bottles and lids is set to double.

"This would probably translate to, in the early stages, somewhere between eight and 10 cents a litre," Viropoulos told 2GB's Ben Fordham yesterday.

"Equivalent to 20 cents a bottle will be the initial impact, so heaven knows where it's going to end up."

He said it was an Australian shortage, rather than a global shortage, as Australia relies on China for its resin production.

"Our only source of resin for blowing milk bottles and associated plastic bottles for drinks and beverages comes from China," he said.

"Now that there's a shortage of petroleum going all over the world, they're keeping the resin for their domestic market and they can't send any to Australia.

"Unfortunately the producers in Australia are forced to air freight it out of the USA at US dollar rates."
