The lucky numbers have been drawn.

The Duchess of Sussex has made a surprise appearance on reality cooking show MasterChef Australia, as her husband Prince Harry jetted off to Canberra on the second day of their tour.

Meghan made a shock appearance at the MasterChef set in Melbourne's inner-north-west, where she appeared as a guest judge for contestants on this year's season.

The Duchess was embraced by fellow judges Jean-Christophe Novelli, Poh Ling Yeow and Sofia Levin after walking into the studio in a black dress.

"I'm so happy to be here," she told the judges.

Meghan has spruiked her cooking skills on two seasons of her Netflix lifestyle show With Love, Meghan.

Meghan was not listed on today's itinerary for the couple's tour, raising questions about how she may have been spending the day.

Meanwhile, Prince Harry spent the morning at Whitten Oval in Footscray, where he learned a few tricks of the craft from Western Bulldogs players and mingled with young fans and members of the Wiggles.

"I still didn't believe it until he came walking out," Western Bulldogs midfielder Adam Treloar said.

"He said he'd never kicked a footy or handballed before. I think he was a bit disappointed we gave him a kids' footy, he wanted a real one."

Inside the club, Harry attended a private Movember event, where he discussed his experience with therapy and touched on the impact fatherhood has had on his life.

"Certainly from a therapy standpoint, you want to be the best version of yourself for your kids," Harry said during the Q and A session, the Press Association reports.

"And I knew that I had stuff from the past that I needed to deal with, and therefore prepare myself to basically cleanse myself of the past."

He was also presented with Western Bulldogs jerseys with the names of his two children Archie, 6 and Lilibet, 4, printed on the back.

A few dozen fans lined Whitten Oval in the hopes of catching a glimpse of the prince, but he slipped in through a side exit and left through a back door.

Dogs supporters said they were pleased Harry was shining a light on an important cause, as well as their club.

"I think it's awesome, you know it's an honour for our club and it's a privilege for him to be at our club," Western Bulldogs fan Irene Chatfield said.

Harry then jetted to Canberra, where he spent the afternoon visiting the Australian War Memorial.

The Duke of Sussex wore a suit and his military service medals as he was shown an Aboriginal and Torres Strait Islander memorial at the venue.

He laid a wreath at the memorial and participated in a traditional Indigenous smoking ceremony.

After meeting with Indigenous veterans and receiving a tour of the commemorative museum, the Prince, once known to his fellow servicemen and women as Captain Wales, rounded out a day of solo engagements with a Last Post Ceremony.

Meghan did not appear at this morning's engagements and is not believed to be scheduled for public or private events today.

Prince Harry will return to Melbourne tonight ahead of a public appearance with the Duchess on the banks of the Yarra River tomorrow.

The pair are set to take part in a First Nations guided cultural walk along the Yarra, which is tipped to be the best chance for the public to see the couple.

Prime Minister Anthony Albanese flagged there could be more trade between Australia and the sovereign state as a result.

The accused said he was unsure his symptoms were real and had received conflicting advice.

The Herald received a preview of some of the drinks on offer in the Gin Trail.

Australia's richest person, Gina Rinehart, could be made to share hundreds of millions of dollars from her iron ore riches after two rival mining dynasties won parts of a bitter legal stoush with the billionaire.

The battle pitted Mrs Rinehart's company, Hancock Prospecting, against the heirs of mining pioneer Peter Wright and engineer Don Rhodes amid allegations of decades-old contract breaches.

Justice Jennifer Smith handed down her more than 1600-page judgment in the West Australian Supreme Court in Perth today.

Wright Prospecting and DFD Rhodes won some of their claims for spoils from the massive Rio Tinto-operated Hope Downs mining complex, in WA's ore-rich Pilbara region.

Justice Smith found Hancock Prospecting would be required to pay royalties, interest and costs, which could be worth hundreds of millions of dollars.

"At the heart of the issues raised by the parties to the proceedings were a number of formal agreements made decades ago between men who were friends or colleagues," the judge said.

"Who, for some years engaged in harmonious and co-operative arrangements to explore, discover and prospect for iron ore in the East Pilbara."

However, Justice Smith dismissed Wright Prospecting's claim for a half share of Hancock's iron ore deposits.

Wright had demanded a stake in mined and unmined Hope Downs tenements and royalties amid a claim Hancock breached a 1980s partnership agreement.

DFD Rhodes also claimed a royalty share of Hope Downs' production over an alleged deal with Mrs Rinehart's father Lang Hancock and Mr Wright that handed over tenements in the 1960s.

The bruising encounter also drew in Mrs Rinehart's reclusive children, over a previous claim by John Hancock and Bianca Rinehart stating their grandfather left them a hefty share in the Pilbara mining resources he discovered in the 1950s.

Justice Smith rejected the children's claim.

Rio Tinto was also a party in the battle as the joint-venture partner in Hope Downs.

Hancock Prospecting said the mining giant would have to pay some of the royalties following the decision.

The royalty share payable to Wright and DFD Rhodes wasn't a significant issue, amounting to about $18 million per year, company executive director Jay Newby said.

Gina Rinehart inherited Lang Hancock's iron ore discovery after he died in 1992. 

But when multiplied by the number of years Hope Downs had been operating, the figure skyrocketed.

Hancock Prospecting rejected the Wright Prospecting and DFD Rhodes' claims during the trial, maintaining that it undertook all the work, bore the financial risk involved in the development and is the legitimate owner of the assets.

Wright said the assets belonged to the enduring partnership.

The result could trigger more costly legal fights, be it appeals against the judgment or to unravel the value of the royalty entitlement.

The 51-day trial, with more than 4000 documents, featured sensational allegations against Mrs Rinehart – which have been vehemently denied – including that she devised an unlawful scheme to defraud her children.

Mrs Rinehart inherited her father's iron ore discovery in the Pilbara region and forged a mining empire after he died in 1992.

She developed mines from tenements at Hope Downs, signing a deal in 2005 with Rio Tinto, which has a 50 per cent stake in the project.

The Hope Downs mining complex near Newman is one of Australia's largest and most successful iron ore projects, with multiple open-pit mines.

Mrs Rinehart's wealth is estimated to be about $40 billion and she is the executive chair of Hancock Prospecting.

No illnesses have been reported, but concerned customers are urged to seek advice.

A state's political donation and campaign funding laws have been ruled constitutionally invalid, in a case that could have national implications.

In a landmark 71-page judgment today, the High Court struck out Victoria's Australian-first political donation rules.

The court found part 12 of the Electoral Act, which regulates political donations and election expenditure, "impermissibly burdens" the Australian constitution's implied freedom of political communication.

Victorian Labor introduced donation caps in 2018, limiting individual payments to candidates and parties to under $5000 each term.

But Labor, Liberal, and National parties were still allowed to withdraw unlimited sums from their respective fundraising bodies, known as nominated entities.

Other parties and independents could not set up their own nominated entities, with West Party candidate Paul Hopper and former independent candidate Melissa Lowe challenging the constitutional validity of the laws.

"All Australian voters want, is a level playing field," Hopper said.

"The High Court has recognised that the two major parties have been rigging the system to stop new parties and independents."

The Victorian government was ordered to pay costs to Hopper and Lowe.

Premier Jacinta Allan said the state Labor government would consider the High Court's decision before responding.

"It would not be appropriate for me to comment without both reviewing the decision and also seeking advice," she told reporters after her new cabinet was sworn in.

In December, Allan announced a bill to allow smaller parties and independents to set up their own nominated entities and cap transfers from such funds at $500,000 for all parties and $50,000 for independent candidates over each election cycle.

However, the reforms were quietly dumped before the legislation passed both houses of state parliament in March.

South Australia, NSW and Queensland have followed Victoria in implementing caps on political donations.

There remains no cap on political donations or spending at the federal level.

Under reforms passed in 2025, the amount an individual can donate to a party's branch will be capped at $50,000 in a calendar year and election spending limited to $90 million for political parties nationwide.

The federal political donation law changes are not slated to take effect until the start of 2027.
